AIBU to think my friend should just accept I am marrying her ex?

I’m 35 and have been with my partner for 4 years. We actually met again completely by chance after many years of not seeing each other, hit it off, were messaging for a week or so and decided to go on a date and he asked to meet up for a coffee and a walk. Before we had even been on our first date, I told my friend that we had hit it off messaging and we’re going for coffee because I wanted to be upfront with her.

He had been her boyfriend at university when they were around 18–20. They were together for about 2 years. They broke up nearly 20 years ago and obviously people change enormously between 18 and 36.

When I told her, after a couple time of meeting him that we are officially seeing each other I specifically asked if she had a problem with it. She said no, so I took that at face value. I wasn’t sneaking around or getting into a relationship with her ex behind her back. I actually even told her before we’d been on the first date.

We’ve now been together for 4 years. We moved in together & he proposed earlier this year and I said yes. We’re very happy, are buying a house together and would like to have children. We have a wedding date set for next June, invitations have gone out and our university friends have been absolutely lovely about it , RSVPs, messages, people booking hotels etc. They’re genuinely excited for us.

When I told this particular friend about the engagement, she said, “Oh, are you going to marry my ex?” I reminded her that we’d been together for 4 years and that I had told her about us from the very beginning. She then said that she’d only said she had no problem with it because she didn’t think we would last.
That has really thrown me.

I completely understand that she might have complicated feelings about it. I’m not trying to tell her how she should feel. But at some point, surely you have to accept that this was a relationship from university when you were 18 years old?

It’s not as though they were together for 15 years, were engaged, had children or had some huge life together. They were university sweethearts for a couple of years, nearly 20 years ago. She has since married, had children and divorced. He and I have now built an actual adult life together over the last four years.

And honestly, I find it particularly difficult because I had exactly the reverse situation myself. One of my friends married someone I had dated at university. I was 18. They got together years later and eventually married and have children. I genuinely didn't have an issue with it. I thought, “We were teenagers at university, life moved on,” and I was happy for them.

So I’m struggling with why I’m apparently supposed to feel guilty now.

I also wonder whether this friendship may simply be worth losing if this is something she can’t move past. Obviously I’d rather not lose a friend, but I don’t think I can spend the rest of my life feeling that I’ve done something wrong by marrying my partner.

All our other university friends seem completely happy for us and are looking forward to the wedding. Nobody else seems to see this as some enormous betrayal.

AIBU to think she needs to let this go? I can understand her feeling upset, but I don’t think she gets a veto over a relationship that started nearly 20 years after theirs ended.

Or am I being completely insensitive about the fact that, regardless of how long ago it was, he will always be “her ex” to her?

Your friend is being ridiculous. Does that mean you can't date someone who she dated at SCHOOL.
What about the lad she had a dance with.

Cue not queue.

You can’t really demand that people say and do things to a timeframe to suit you.

In the early days it may have seemed to her too much to essentially ask you not to date him - it’s not as if they’ve only recently split whatever her residual feelings. And it may not have worked out anyway. If she had said it then you would have thought she was BU then too for different reasons. I don’t think there is a right time to say it.

It’s really not on to correct people’s grammar and spelling, and it can get you deleted. There are people of all abilities and some disability posting on MN so drawing attention to such mistakes may be highlighting a disability they may not have wanted to disclose - and now you’ve forced OP into disclosing she’s dyslexic.

And they’ve been together for four years - living together in fact. At what point do you think friend should have worked out that this was a long term relationship after all this time. There was a right time to say something. When OP first asked.

I wouldn’t have got with my friends ex. It’s weird.

In most friendship groups, it is considered off limits to even date someone one of your friends has previously dated.

Just as some Mumsnetters think it is off limits to date your best friend’s sibling or your sibling’s best friend. Both bonkers rules IMO.

I have to say, I’ve never understood this either. Who better to date than someone already known to you? Unfortunately lots of friendships don’t last long term, people change, move away etc. But a successful relationship can end in marriage, children, sharing a life together, who would want to prevent you from having a chance at happiness?

ilovesushi · 15/08/2026 15:29

Not come across this moral code before that anyone you ever dated no matter how far back in the past is off limits for friends. Seemly a lot of people subscribe to it. Personally if a friend met an ex of mine after we'd broken up and they hit it off, established a long term relationship and were getting married, I'd be pleased for them. If I felt sour about it, I'd keep it to myself and not upset my friend with my own personal feelings.

Perplexin · 15/08/2026 15:28

My Sister married my ex and I was maid of honor 😅

There was 6/7 years between us dating. I couldn't be happier for my sister and her husband. They're happy so im happy. Im not bothered one bit. They now have 3 children together and are happier than ever. Im not angry, sad or jealous.

The only thing I can think of is based on posts by OP is that maybe her friend isn't completely over the guy? Unfinished business with how they ended maybe?

I think the friendship has ran its course and its time to slowly fizzle out.

She is entitled to feel however she feels but considering the time duration, it just seems a bit odd that she has suddenly developed an issue.

Congrats OP.

Are you for real?? This was over 20 years ago! 🤦‍♀️🤯🤦‍♀️

It wasn't over twenty. Op was exaggerating when she said 20 and now you're exaggerating again. Nonetheless it was a long time ago.

whackwhackoops · 15/08/2026 15:24

Firstly, congratulations I might be wrong but assuming this is your first marriage and you might want to have children with this man (sorry if presuming too far) it’s lovely you have met your future husband.
I’d be interested to know if at the time you started dating and she said she didn’t mind,
she was happily married? Has she divorced in the last 4 years you have been together and now is a bit jealous or bitter of your happiness?
id be peeved if a friend said this to me when i announced an engagement. I don’t think you sound smug fwiw. If the other uni friends as happy for you both then don’t let her comment overshadow your news. she might even say something nice in future if she knows others don’t share her opinion. Surround yourself with those who celebrate your news.

Pistachiocake · 15/08/2026 15:22

You've done nothing wrong. She can't help it if she feels weird about it (many of us think about exes from the old, simple carefree days before life really hit us, so maybe this interrupts a kind of daydream for her) but she is being unreasonable to say this to you.
Do you have mutual friends, as in will it be awkward? Because very few of us regularly mix with the same people as we did a couple of decades ago, so unless this is the case, just try not to have them together too often.

I voted YANBU. However I can see both sides.

On the one hand it was years ago and she clearly moved on getting married and having children (even though that marriage didn’t last). She should on paper not have a problem with it as it was a long time ago.

But the relationship was obviously very important to her and shaped her life at university for 2 years. I assume
that’s where your friendship stems from too so I do appreciate how weird she probably feels about it being together with you both as it will bring back memories of the 3 of you together (albeit the dynamics being different).

You say you don’t want to tell her how to feel but isn’t that what you are doing? By expecting her to be over it. Obviously you can ask her to stop referring to him as her ex (but technically that’s true). I think it’s probably better for both of you if the relationship ends which is sad on both fronts after all these years but that’s why you shouldn’t date a friends ex no matter how long ago as true long standing friends are hard to come by.

He’s her ex, of 20 years ago. Not her property.

Are you serious WTH I'd be pissed too ☹️ I certainly wouldn't be ok with it what did you think would happen if you got with your friends ex? Your no friend to anybody I'd cut contact with you

Have you actually read the OP?

MyDpsanarse · 15/08/2026 15:10

I wonder if your friend's feelings are more to do with him dumping her for his education, he didn't really care for her that much but maybe she saw him as a much longer term relationship. Now she's divorced she sees him as the one who got away and hoped one day they'd find their way back to each other, that's why she thought your relationship with him wouldn't last because he was meant to be with her.
It seems your DP didn't see her that way, he went away and forgot about her. This friendship isn't going to last Op, especially if she finds out how your DP feels, so just get on with the wedding. It's sad for your friend but she needs to face the truth and stop harassing you

And do NOT invite her to your wedding.

Oh God, yes, this. There’s clearly a lot of resentment there and the last thing OP needs is her friend watching them get married and then pouring alcohol on it afterwards.

ThreadGuardDog · 15/08/2026 15:01

Lugol · 15/08/2026 14:59

I'm sure OPs friend intends to do exactly that and hopefully find friends who don't tread where she's been before.

She’s had four years to do that. They moved in together, what did friend think was going to happen ? I get the feeling she was waiting around for it to fail. Which is not very nice.

Middlemarch123 · 15/08/2026 15:01

I don’t think the way your friend is responding is only because of her feelings for him.

I think it could well be that she isn’t currently in a good place. She’s divorced, that has a big impact on anyone, especially the break up of a long marriage with children involved. You can’t really envision it until you experience it. She may well be ruminating on all her past relationships too much. She could even be blaming herself for losing her first love. And the first love always matters.

I think if she was fulfilled now, with or without a partner, she might be able to feel genuinely happy for you both.

I hope you and your partner have a long happy relationship. Personally, I wouldn’t cut her off or do any more soul searching. I’d leave the door open because hopefully she will find happiness and be in good place too.

Lugol · 15/08/2026 14:59

BettyJoanPerske · 15/08/2026 12:54

Of course not, but she is still being unreasonable to be dramatic about it. If she's not okay with it she needs to fade away quietly, not play the victim.

I'm sure OPs friend intends to do exactly that and hopefully find friends who don't tread where she's been before.

ilovesushi · 15/08/2026 14:54

She's mental. Four years of you going out and she still hasn't moved on from him being her ex decades ago. She's got some serious issues if she can't get over it. She is totally unreasonable for mentioning it to you.

What outcome does she want? "Friend, I understand your feelings and so I am going to call off my wedding to my partner of four years. I am sure that was the only thing getting in the way of your one true love. I will stand aside for you now."

Don't sweat it. Lose the friendship.

BePearlTiger · 15/08/2026 12:28

Fair enough I think I can make a post to rant about something without needed to apply every little detail verbatim

I couldn't understand from the info given in your original post why you had a problem with her reaction.

Now you've given details of what she has actually said to you it makes more sense of your initial complaint.

No you don't have to give every tiny detail, but more than you said in your first post was definitely needed.

But OP was upfront with her from the start - her friend had no problem with it. That was four years ago and they’ve been together ever since. And it turns out that the friend was only OK with it because she didn’t think it would last. Well she should have said that from the start shouldn’t she ? It’s batshit to try to police the relationship now.

BePearlTiger · 15/08/2026 11:28

I haven’t said she isn’t allowed to feel how she feels. I just think it’s been almost 20 years she met and married and had children since then. She couldn’t even remember what undergraduate degree he studied. I think it’s safe to say he’s changed a lot from age 18 to 36.

Well, you have actually. It's in your very title.

You want her to "just accept" that you are marrying her ex.

In most friendship groups, it is considered off limits to even date someone one of your friends has previously dated. But here you are, expecting her to "just accept" you marrying her ex, minimising the time she spent with him, minimising or brushing off that he may have had any significance to her, while pointing out he ended it. Saying she doesn't even know him.

I wonder how he would feel, were he to read them, about your callous words about her.

lulubalu · 15/08/2026 14:38

Wow OP, you've somehow stirred up a right hornet's nest here
Maybe you've hit a sore spot with some posters
Fwiw I would have zero feelings if you told me your were going on a date with my 'first love' from my Uni days.
The only surprise bit would be to suddenly have him back in my orbit if we were for example to start hanging out on double dates.
If you subsequently decided to marry, I hope I'd be happy for you.
The thought that you shouldn't date a friend's ex really depends on the circumstances and in the scenario you describe, your friend is being a bit ridic (IMO)
In your shoes, I'd crack on, marry the man, ditch the friend and (hopefully) live happily ever after. The End.
