Looking for perspectives on the following:

Would you attend your adult DC’s wedding if they had invited their father’s mistress? Would it change if the affair was years ago? Would you feel disrespected?

Prioritise your mum.

Your dad has a choice over who he prioritises - you or the ex-mistress.

@Zoobaloo whilst the situation was very hurtful for your mum, your dad has chosen to have his life spent with this other women rather than your mum. The upset has ruined enough, and your mum needs to accept the situation so that it doesn’t ruin anymore. You should have your dad there with his wife if you want your dad at your wedding.

This set-up should start now as they’ll be plenty more events where all 3 need to attend should you go on to have kids.

Your mum needs to be the bigger person here, and you need to help her do that by not putting her feelings before your own.

*missed off quote, but this is in response to OW name calling.

Ah wait…changed my mind. That bitch can whistle, your dad too for allowing her to name call the mother of his childen

Jopo12 · 03/08/2026 00:33

Invite your mum and dad but not the be wife.
Then it's his choice not to come and your mum will have a nice time at your wedding

I don't think the victim should bear the burden of suffering in order to keep the man who treated her badly happy. That's just letting him get away with being a prick, and punishing her for his cruel behaviour.

Perhaps instead of that, the father should try being a decent person for once and recognise that he did a horrible thing, and because of the choices he made his new wife is reasonably not welcome at family events, so he'll have to attend alone.

DoubleBoubles · 03/08/2026 00:40

You don’t like her so don’t invite her
Up to your Dad what he does but of course he will choose her.

I don’t want a relationship with her at all, or for any future children to. I’m civil with my dad because he’s my dad but I don’t like his wife. Affair aside, she isn’t a very nice person and is very nasty towards my mum, calling her names like a teenager in high school

'very nasty towards my mum, calling her names like a teenager in high school'

How do you know this? Has she done this in front of you?

Regardless. I would definitely not be inviting her. And if your Dad chooses her 'hurt feelings' 🙄 over seeing his daughter get married then that's his loss. And you'll know exactly where you stand with him.

Tbqh, he sounds awful. Only a completely heartless bastard would put your mother in this position on her daughter's wedding day.

Saying that, I hope you manage to sort all this out and have a wonderful day. 💐

Her now being his wife I think changes things. If it was temporary then no. But wife suggests an intention to be permanent. He shouldn’t have cheated of course but it is what it is now. So yes I think she should be invited. But no one should be threatening not to attend. And if it will cause issues she should maybe bow out gracefully.

Did you read the bit where the op said she is nasty to her mum and calls her names like a teenage bully in school?

What he did to OPs mother is separate to the relationship he has with his daughter. It always will be. OP needs to move forward and not have to carry the burden of this.

TurnhamQueen · 03/08/2026 00:51

Sorry to say it, but your Dad is a piece of shit.

He prioritised this woman over your Mum, humiliating both (you mentioned “several affairs”).

Now he’s prioritising the woman (who also sounds like trash TBF, if she’s name calling your mother) over you.

Tell both to get to fuck and invite neither. Your father has already shown you who he prefers once, don’t give him a chance to disregard and disrespect you and your mother a second time.

changeme4this · 03/08/2026 00:51

If I was the wife, I would want to know that others will feel uncomfortable about my attendance and I would decline but encourage my Hubby to attend for his Daughter's sake.

I don't know how you can broach that with her though.

Next up will be the tough discussion on seating plan... I wouldn't want my Mum to be hurt having to share the family table with her.

  1. The title is AI generated through Mumsnet and I forgot to change it. This is about my mum and dad. Sorry for the confusion!
  2. Dad had an affair multiple times with the same woman and is now married to her. It caused an ugly divorce and lots of heartache for my mum.
  3. Dad wants his new wife at my wedding. I don’t agree but he won’t come without her. I don’t think it’s fair to mum.

I wanted some opinions to decide how to navigate this going forwards

It seems very easy. Dad is invited if he comes alone. End of. Mum is invited.

All OP said was that the affair was years ago. She’s not said what age she was when it all happened or
if her stepmum was in her life when she was younger.

no my Dd doesn’t know any of the background but is now starting to see her dads gf’s behaviour (eg very controlling and selfish) but it’s never come from me.

I have not intentions of telling her any of this as I want her to have a good relationship with her dad for her own sake. However I can’t guarantee she won’t fallout. Exh has a massive family and many of them have fallen out with exH and his gf over the years - they are now estranged but have regular contact with my Dd. I’ve allowed contact on the agreement my Dd will be left out of family politics and bad mouthing of her dad. Unfortunately that will be harder for me to influence when she’s an adult

She is not a “stepmother”. The OP does not refer to her as “stepmother”. She doesn’t want her at her wedding.

Lilypad789 · 03/08/2026 00:53

Oh I think it would be awful to invite her. I’m so sorry because that doesn’t help you at all but your Mum gave birth to you. Assuming she’s been a good Mum then she may have dreamed of this day for decades. He hurt her, they hurt her and broke what she thought was her life. How awful for you and your Mum. Your Dad should understand why this is a hard no IMO. I would rather have my Mum happy with my Dad absent but only you can decide really.

Gateappreciation · 03/08/2026 00:55

Depends how long your dad has been married to his wife. If they’ve been married a long time, then I can see why your dad would want his wife there, as as a guest, rather than main wedding party.

LilOleMe2 · 03/08/2026 00:59

It is highly irregular, and very pointed to invite someone, let alone someone close, to a wedding without their spouse. I think your mum needs to suck it up for one day.

What he did to OPs mother is separate to the relationship he has with his daughter. It always will be. OP needs to move forward and not have to carry the burden of this.

So why is your belief that OP's mum has to suck it up and suffer, instead of her father? Surely an appropriate compromise would be that her father doesn't expect his affair partner to attend family events, and in return, her mother is civil and polite to her father and doesn't cause a fuss.

Anyway, it's only separate if OP feels it's separate – her father's hurtful, unethical behaviour also impacted on her and the structure of her family, and however she feels about that is valid. So if she feels that her father's behaviour has diminished him in her eyes, that's entirely valid, as is wanting to prioritise her mother's happiness over her father's happiness.

She doesn't 'need' to move forward from a dislike of her father's behaviour, or his new wife – her father needs to prioritise his daughter over his dick, and accept that he's being unreasonable to expect his children to accept his affair partner. Simple.

It sounds clear cut. Your mum should be the absolute guest of honour. She should not have to endure the presence of the OW.

I think you should just invite your dad. If he doesn’t want it come without his fellow homewrecker, then it’s fine for him not to come.

My dad and his mistress are married now. Even though my mum is now dead, I am NC with them. They are a horrible pair of narcs. It’s been nearly a decade of NC and I have zero regrets.

No way would I invite her then.

RestingRoundFace · 03/08/2026 01:21

Your dad said he won't come if he can't bring his nasty wife
It sounds manipulative
You should tell him he can't come if he brings her.
He's putting her first again by giving you this dilemma.
Give the dilemma to him by sticking to your guns. He can ponder over it, not you

thereisnomeaning · 03/08/2026 01:36

In the mother's place, I would suck it up and deal with it for the sake of my child. I do think being sat in a different place in the reception is a reasonable ask though.

It's really up to you to decide what you are comfortable with. You have every right to invite your father but not his wife. Of course, he may then decide not to come, which you'd have to accept.

I don't think there is a right or wrong and I'm not sure you can avoid upsetting someone. Decide what you think is right and then let everyone else decide how they want to handle it.

I think if your father would be wrong not to attend if invited without his wife, but that's up to him.

Well, if she behaves like this towards your mother, I think it would be easy for me. I wouldn't invite her and would accept it if my father then decided not to come.

My exH is now living with his affair partner (they began an affair when I was pregnant and it went on through the first year of my DDs life - so a really vulnerable time for me). I also knew the affair partner prior to affair so she knew I existed and that was pregnant/had a new baby etc.

They now play happy families with my Dd (now a teen) 2 nights per week. Obviously I don’t love the situation but would never bad mouth either of them and my Dd is still oblivious to all the background.

if they’re together by the time my Dd gets married, I will basically be in the same scenario as your mum in this situation.

would I choose to spend time in the company of either my exH or his affair partner? NO WAY

would I be willing to be civil for one day for my dds sake and bite my tongue? ABSOLUTELY, it’s her day. She deserves to be happy and would want both me and her dad there.

my DDs wedding is not about me - or her dad - or any historic drama. It’s about her and her new husband and their future. In fact I’d put on a brave face and not even let on to my Dd that o had an issue with it. It’s not fair to put that on her.

if she happens to grow up and see through them both and decide herself she doesn’t want her dads partner there I won’t pretend I’d be gutted 😂 but that will never come from me or my influence

I am in the same position as you. There's a lot of years until this scenario would play out for me. But if my child wanted her there I would accept that for their sake.

But in the OPs case she doesn't want the new woman there so shouldn't invite. I imagine her dad will end up going even if she's not invited. But if he doesn't that's on him.
