My mum and my mother-in-law disagree about the wedding. What do I do?

Speak to them calmly, lovingly and with compassion, reminding them that this is your day, and it's up to you to do whatever it is that you want to do. They may disagree with that, but they should be more focused on your happiness, and on the couple's happiness.

Family dynamics always get insanely interesting when you're planning a wedding.

Your no can be a full sentence

You can just say no to family about the wedding. It's your wedding. We have this strange misconception that we're doing this for our families, and in some cultures that may be more the case, but you're getting married because you want to get married. Your no can be a full sentence.

It's impossible to throw a wedding and keep everyone happy, and it's important you remember that from the beginning.

Seven things to say to your mum or mother-in-law (or mom)

1. Start soft, and describe what happened

The Gottman Institute calls this a softened start-up: describe the situation without judgement, say how you feel about it, and ask for what you need in positive terms (Karen Bridbord, The Gottman Institute, updated 18 May 2026). Nonviolent Communication has a test for the first part: say what a video camera would have picked up, and a camera doesn't pick up someone being "rude" (Alan Rafael Seid, PuddleDancer Press, read 7 November 2026).

Say: "Mum, you and his mum have both rung me about the flowers this week, and I'm feeling stuck in the middle. I need the flowers to be our decision, and I'd really like your help with something else."

Instead of: "You're being controlling about the flowers."

2. Listen for what she's actually after

Your future mother-in-law has opinions about the napkins because the napkins are a proxy for control, for being heard, for mattering in her child's life.

The Center for Nonviolent Communication describes empathy as listening to what someone is going through, rather than jumping to advice or reassurance (CNVC, What is NVC?, read 7 November 2026).

Say: "It sounds like it really matters to you that your side of the family feels welcome on the day. Have I got that right?" Then stop talking and let her answer before you say what you've decided.

3. Stop carrying messages between them

Bowen family systems theory calls three people "the smallest stable relationship system": when two people are under strain they pull in a third, and the tension moves round the triangle without getting settled (The Bowen Center, Triangles, read 7 November 2026). If you're passing notes between two mums, you're the third corner.

Every family has unspoken rules about whose feelings matter most, who gets to make decisions, how conflict is handled. Planning a wedding forces every single one of them into the open.

Say: "I'm not going to pass that on. If you want to talk to his mum about the seating plan, ring her, or we can all sit down together."

4. Give each of them a job that's only theirs

Wedding writer Jen Glantz suggests giving your mother-in-law a list of tasks she can own and letting her do them her way (TLC, read 7 November 2026).

Give your mum one job and his mum a different one, so they're never deciding the same thing, and only hand over jobs you can genuinely let go of.

Say: "Would you take on the welcome drinks? They're yours from start to finish, and I'll stay out of it."

5. Ask for one thing she can actually do

In Nonviolent Communication a request is specific, doable and in positive action language, and it only counts as a request if you can hear a no (Seid, PuddleDancer Press).

Say: "Could you send me your must-invite list by Sunday? We'll decide the numbers together, and we'll tell you and his mum on the same day."

Instead of: "Can you stop interfering with the guest list?"

6. Say no once, then say it again

Your no can be a full sentence.

Cleveland Clinic social worker Karen Salerno's steps: know what you need, say it directly with "I" statements, say what you'll do if it isn't respected, and follow through (Cleveland Clinic, 13 February 2026). The broken record technique, which Psychology Tools credits to Smith (1975), is calmly repeating the same message without raising the stakes, however many times you're pushed (Psychology Tools, read 7 November 2026).

Say: "We've decided on a small ceremony, and that isn't changing." The second time, the same words. If it keeps going: "I've told you what we're doing. If we keep going round this, I'm going to leave it for today."

7. Stop when it's too hot, and say when you'll come back

The Gottman Institute's advice for an argument where someone is overwhelmed: take a break of at least twenty minutes, don't rehearse what you'll say while you're away, and come back within twenty-four hours; whoever asks for the break is the one who picks it back up (Alexander Elguren, The Gottman Institute, 30 October 2026). It's written about couples, so treat it as a starting point with a parent.

Say: "I'm too wound up to do this well right now. Can we pick it up tomorrow after lunch?"

When to bring in your partner

As with most wedding planning conversations, this one should start openly and honestly with your partner.

Glantz's advice is to tell your partner what's happened and ask them to help find a fix or talk to their mother directly (TLC).

Bring them in:

• Before either mum hears a decision. Agree it between the two of you, then tell both mums the same thing on the same day.

• Whenever it's their mum. They have the conversation; you're in the room if you want to be.

• When the same row keeps coming back.

• When it's stopped being about the wedding.

Do what makes you happy. Everyone else will fall into line. And if they don't, then I think it's a deeper issue at play, as opposed to their opinion on what your wedding should look like.

If it's the deeper thing, talk about it as a couple first, away from the planning, and think about a family or couples therapist for that part.

A breath before the hard conversation

You have about six seconds before you say something that's going to cause issues for the rest of your married life.

Before you ring her, or before she arrives, find five minutes alone: car, bathroom, locked bedroom door. Inhale for four counts. Hold for four. Exhale for four. Hold empty for four. Repeat for two to three minutes.

If it flares while you're talking: inhale through your nose for a count of four, hold for seven, exhale through your mouth for eight. Once, maybe twice.

This doesn't make you agree with her. It buys you seconds to decide if this fight matters, and if so, how you actually want to have it. Some fights matter. Some absolutely don't.

The whole essay: Three breaths between you and telling your future mother-in-law to fuck off.
