In-law problems: how to set boundaries as a couple

The Real Question: Whose Side Is My Partner On?

Most advice on this topic is about the mother-in-law: what she says, how she interferes, how to cope with her. But when people bring this problem to a psychologist, the sentence that hurts most is rarely about the in-law. “When his mother says something, he just goes quiet.” “She never says no to her parents.” “Every time we argue, my partner takes their mother's side.” What hurts is not only the interference. It is being left alone in that moment.

So the question here is not “how do I deal with my mother-in-law?” but “how do the two of us stand on the same side?” The frame is simple: the couple is a team. The family sits outside that team, loved and respected, but not a partner in the couple's decisions.

If you want to see how much family tension is affecting the rest of your relationship, the free relationship assessment is a good starting point. It takes about 3–4 minutes, needs no sign-up, and your answers stay on your device.

Close to Their Family, or No Boundaries at All?

“My partner is too close to their mother” can describe a real problem, or simply two different family cultures. Someone who calls their mum every day and loves Sunday lunch with their parents is not automatically without boundaries. In some families, that is just what closeness looks like. The measure is not how often they are in touch, but who is making the couple's decisions.

Becoming an adult does not mean loving your parents less. What changes when you build your own household is the order of priorities. Love and respect for parents continue, but decisions about the home, the children, money and privacy now belong to two people. When one partner cannot make that shift, the other starts to feel they come second in their own relationship.

Being close to family is not the problem; the problem is when the family makes the couple's decisions.

If you recognise your relationship in the right-hand column, it does not mean your partner doesn't love you. Often your partner is caught between a loyalty learned in childhood and the family they are building now. They may fear hurting their parents, upsetting their mother, or hearing “you've changed since you got married.” That fear makes boundaries genuinely hard for them. Hard, though, does not mean unnecessary.

If reading this you realise the deeper wound is not the in-laws but trust between the two of you, the free relationship assessment can help you see where you stand on communication, conflict and connection. There's no sign-up, and your answers never leave your device.

Who Sets the Boundary, and with Whom?

A lot of in-law conflict comes from the wrong person trying to hold the boundary. When a daughter-in-law objects directly to her mother-in-law, or a son-in-law to his father-in-law, the family often hears it as an outsider attacking them. When the same sentence comes from their own child, it is heard as a family conversation. That isn't fair, but it is usually how it works.

So the general rule is: the couple decides the boundary together, and each partner speaks to their own family. You talk to your partner; your partner talks to their mother, father or siblings. If the difficulty is with your family, the roles swap. This way nobody has to go head to head with their partner's parents.

There is one exception to this rule. If someone is openly rude to you or insults you, you don't need to wait for your partner. You can protect yourself with a short, calm sentence. Saying “I'm not willing to be spoken to like this, so I'm going to step out” is not disrespectful.

Agreeing on House Rules: Visits, Childcare, Privacy

A boundary is not something shouted in the middle of an argument. It is a rule you have agreed on beforehand. Boundaries set in the heat of a fight tend to feel like punishments and collapse at the first test. Rules you have talked through calmly become ground you can both stand on.

1. Write down the hard situations separately

   Each of you lists the three situations you find hardest, such as unannounced visits, interference in decisions about the children, or your arguments being reported to family. Describe situations, not character.

2. Turn each one into a request

   Instead of “your mother needs to stay out of it,” try something workable: “Can we agree on weekend visits in advance?” The more specific the request, the less likely it is to turn into a fight.

3. Look for common ground

   Take into account your partner's love for their family and their sense of responsibility. The goal is not to shut the family out, but to find a middle path you can both live with.

4. Decide who says it, and how

   The family's own child delivers the rule. Agree together on the wording, the timing, and whether it happens by phone or in person.

5. Review it after a few weeks

   Sit down and look at what worked. A rule that doesn't hold the first time is not a failure; it is a draft to adjust.

The most common topics for shared rules are how often visits happen and whether people can drop in unannounced, who has a key to your home, decisions about childcare, whether financial help from parents comes with a say in your life, and whether private matters get shared with family. The complaint “my partner tells their mum everything” usually belongs to that last category. It more often comes from habit than bad intent. Still, privacy is a right you both share.

Scripts That Don't Turn into a Fight

The most common reason these conversations blow up is that they become about the in-laws' character. “Your mother is so selfish” pushes your partner straight into defending her; the topic is no longer the boundary but protecting their parent. Talking about behaviour, feelings and requests works far better.

When You Talk to Your Partner

1. “I'm not against your mum. I need to feel that you're with me.”
2. “Yesterday, when your mum stepped in about the baby's bedtime, I felt alone. How can we handle that together next time?”
3. “I don't want our arguments shared with your family. Can we keep those between us?”
4. “I want you to see your parents. I'd just like us to plan visits together first.”
5. “We both have a point here. I'd like to understand how you see it first.”

When Your Partner Talks to Their Own Family

• “Mum, I love you and I know you care about us. We made this decision together, and we're sticking with it.”
• “If you let us know before you come, we can actually make time for you.”
• “I'm not okay with my partner being spoken about like that.”
• “I'm not going to discuss our relationship with you. That's between us.”

One detail matters a lot: when your partner speaks to their family, the rule should be framed as “we decided,” not “my partner wants this.” The first makes the couple look like a team. The second turns you into the target.

When Your Partner Acts Differently Around Their Family

“My partner changes when their family is around” is one of the most common things people describe. A partner who is warm at home may become more distant, quieter, or even more critical of you at their parents' house. Sometimes a joke is made at your expense and your partner laughs along. For the person on the receiving end, that can feel deeply lonely.

Behind this change there is usually not a conscious choice but an old role. When people walk back into their childhood home, they tend to slip back into their old position there: the good child, the son who never upsets his mother, the daughter who keeps the peace. Your partner may not notice it at all. So it helps to raise it not in anger, but calmly after the visit, with one concrete example: “When your mum made fun of my cooking, you said nothing, and I felt alone.”

If this conversation gets stuck in the same place every time, the problem may no longer be the family but the cycle between you. Our guide on having the same fight over and over looks at that cycle in detail.

In-Laws After a New Baby

A new baby is one of the times family boundaries are tested most. Grandparents often genuinely want to help, and with the help come opinions, experience and sometimes a wish to make decisions. For two exhausted, sleep-deprived parents, that can be both support and pressure.

• Before the birth, agree on how often visits will happen in the first weeks and how long they will last.
• Agree that decisions about feeding, sleep and health belong to the parents, and that on health questions you follow your healthcare provider's advice.
• Make help concrete: bringing a meal, taking on laundry, holding the baby while one of you sleeps.
• Prepare a sentence your partner can use with their own family when criticism comes: “This is what we've decided to do.”

The couple's own relationship also gets reshaped after a baby, and tension about family often lands on top of that exhaustion. Our guide to your relationship after a baby looks at this stage from the couple's side.

“I Can't Stand My Mother-in-Law”: What to Do with That Feeling

For someone who has been hurt, belittled, or has spent years feeling that their partner's family doesn't want them, not wanting to see the in-laws is understandable. Accepting the feeling without judging yourself is the first step. But there is a difference between a feeling and a decision, and it is worth talking that difference through with your partner.

Some couples find a middle path: shorter visits, seeing the family only on certain occasions, or your partner sometimes visiting on their own. Asking your partner to stop seeing their family entirely, on the other hand, often puts them in an impossible position. If there is serious, ongoing mistreatment, the situation is different; see the last section. Questions about legal or religious duties, such as caring for elderly parents, are outside the scope of this guide and are best taken to the relevant professional.

For the Partner Caught in the Middle

You may be reading this as the one stuck between your partner and your family. If so, you are probably being blamed from both directions: by your partner for not protecting them enough, and by your family for changing. That is an exhausting position, and guilt is very common.

• Listen to your partner's complaint not as an attack on your family, but as information about your relationship.
• Explain the boundary to your family in “we” language, and tell them you love them too.
• Practise tolerating your family's disappointment; someone being upset does not mean you did something wrong.
• Don't criticise your family to your partner, or your partner to your family.

When Boundaries Aren't Respected

Sometimes a couple agrees on a rule, the partner talks to their family, and nothing changes. At that point a boundary is no longer about changing other people, but about deciding what you will do: ending a visit early when the rule is broken, not reopening the same debate, or no longer sharing certain topics with the family.

If your partner doesn't keep to the shared rule, or sides with their family every time, the issue is no longer the in-laws; it is trust between the two of you. That may be a good moment to consider support from a couples counsellor. If you have started wondering whether to stay in the relationship at all, our guide should I leave my relationship? takes that question slowly.

If your partner's family shouts at you, insults you, threatens you, or pressures you in the name of family honour, this is not a boundary issue but a safety issue. In an emergency call 911 in the US or 999 in the UK. The National Domestic Violence Hotline (1-800-799-7233) and the UK National Domestic Abuse Helpline (0808 2000 247) also support people facing abuse from their partner's family.

Learning to talk about family without either of you getting defensive can take time. In Blisswell Couples, communication and conflict are worked through in a structured way: you each answer the same questions on your own phone, and the answers are then placed side by side.
