Me and my partner and his ex affair partner.

Suneptune · 06/09/2025 00:23

I have been with my partner for 9 months. I was married for 25 years and separated and then divorced 5 years ago when my ex informed me out of the blue (to my utter horror and complete shock) that he had slept with multiple women including at least one of his exes (who I considered a friend of mine) and with several women I knew. The divorce was brutal (him not me). I moved away and have not seen him since the separation 5 years ago. I had to make a new life. I did not know who to trust. Life as I knew it had ended. It was tough and lonely. I had a lot of therapy. I didn’t date.

i have always valued fidelity and honesty and my ex knew this. It was one of the reasons he married me he said. I have always said that I could never be with someone who cheated and even my friends I have realised are all faithful types. I suppose like attracts like. Famous last words.

My new partner on our first date told me that he had cheated on his wife 10 years ago and that they had recently divorced (married for 20). He said he was ashamed of his behaviour and regretted what he had done. So I decided to give us a chance. He was loving sweet tender to me.

I then found out that this affair lasted a year and that his affair partner had herself had several affairs during her marriage. The first man involved with her was absolutely “cut up” apparently by their affair ending and he was the second. She has been with her new partner for several years now. His wife found out a year after the affair and he chose to stay with her and their children.

Then he told me over the next few months firstly that he had cheated on his first wife who he was with for 10 years with a random woman who threw herself at him. He also had a fling with someone he met in a pub during his second marriage.

Lastly, I now know that he is still in contact with the affair partner who works for the same organisation as him though in a different office. I thought at first that they saw each other only every so often at the odd social event but it now transpires that last year, they both signed up for a voluntary project (with about a dozen others) and saw each other several times through this. Some weeks after the project was over the two of them then went to a blues club that they had gone to during their affair (her suggestion).

He then started to date me.

Then this summer they both signed up for another voluntary project. I was upset. He told me that she had moved on with her life when I asked what was going on. He said that he had the utmost respect for her in her professional life. He said I was the most important woman to him. He said he needed me to trust him. They saw each other (together with the rest of the team) two or three times a week for this project and there was a lot of socialising in pubs also. On the final very intense day of the project (there was a party afterwards), he didn’t text me at all and not even to say goodnight.

For the last few weeks I feel as if I have been on a choppy sea. He knows this and has said that it was a difficult time for me. He also said that just because I don’t see my ex and the people who betrayed me in my previous life, doesn’t mean that he can’t see her. I said to him that I do not mind him seeing his wives of course not. It was just that I was concerned about the affair partner and that I felt that she was a third party in our relationship. It seems to me (though I didn’t say this to him) that this woman was exactly the sort who my ex husband would have slept with. I don’t want her in my life. My partner told me some ugly details of how they conducted their affair which made me want to cry.

I wonder if he is less loving to me since the ending of the project (doesn’t use my nickname) and the tone of his texts seem to have changed though I could be reading too much into this. He says I am judging him and that he has changed. Do cheats change? Perhaps for him she’s the one who got away? What about the project next year? There’s other stuff but I have gone on enough.

Stop dating him. He lied by omission and this and his other actions indicate he’s untrustworthy.

Being single or free to date others would be much better than spending more of your time, resources and energy on him.

Arlanymor · 06/09/2025 08:34

He’s a serial cheater and took both of his marriages so lightly that he set both of them on fire with his behaviour. Don’t wait until he makes you wife number three and does exactly the same to you. I believe people deserve a second chance but not a third, fourth, etc. For your own sanity and self-respect leave him now before you are hurt any further - you deserve better.

frankiesgrace · 06/09/2025 08:40

He and her have no morals and are probably in more contact than he’s told you, and very likely still sleeping together. I’ve been where you are.

The sad thing is, if they truly loved each other they’d just go and be together, but instead they will hurt other people whilst carrying on with their behaviour instead.

I know it’s hard, particularly building yourself back up after an unexpected marriage breakdown, I’ve been there too. But your confidence and self esteem will be in tatters if you stay in this relationship a moment longer.

Frankenbetty · 06/09/2025 08:45

I honestly think most women are better off without men!

Blueuggboots · 06/09/2025 09:10

Fuck this drama! Get rid of him.

Kidsgotothatschool · 06/09/2025 09:44

He’s hiding in plain sight.

And you’re feeling anxious because he is not safe emotionally, mentally and sexually.

Ditch him - and when someone tells you who they are in the future believe them!

Unexpectedlysinglemum · 06/09/2025 10:03

There are some people who don’t really cheat at all but might have exit affairs (like an ex of mine) and then be mostly faithful (as much as we want to believe he’ll cheat on the other woman too, this kind of person won’t usually bother)
and there are other cheaty type people who love the thrill of seduction and will always be flirting and looking for chances to stray as they love the ego boost. He sounds more like the second and so does the company he keeps. Stay away.

Wishimaywishimight · 06/09/2025 10:18

Why on earth are you putting yourself through this? You had no choice last time as your DH was not honest with you at the time but this time you are chosing, despite the importance you say you place on fidelity, to stay with a known cheat who continues to have significant contact with an affair partner.

Do you think he is magically going to change?

Your first mistake was ignoring a red flag on the FIRST DATE! Don't compound that by staying.

Suneptune · 06/09/2025 10:20

Thank you everyone genuinely. I m new to mumsnet and just desperate I suppose for some sort of connection with others with all of this. Quite tearful. I’m actually quite alone after the divorce. My ex was the person I would have talked to if he hadn’t turned out to be a wolf in sheep’s clothing. Horrible terrible irony.

My head is spinning.

the problem is that I no longer trust my instincts- I thought my ex was a good faithful man who loved me and had no inkling whatsoever of his double life. And I consider myself to be an emotionally intelligent person. Clearly not.

Sorry to add extra facts (but I was so exhausted after writing the post last night and it was so long and garbled already) but anyway here are a few more.

After the project was over, after a lovely dinner he suddenly started going through the entire history of his ex affair partner with the company vis a vis him (when she started there, when the affair started, committees they were on together and had to leave because of the tensions after the break up etc). I was clearly uncomfortable (thinking why on earth is he doing this?) but he went on and on and on for about half an hour .

Then last week, he said he wanted to show me the photos on his phone of the project and there were dozens of photos with her in them. So I know what she looks like now. I didn’t before. It makes it all more real and threatening. She is the opposite of me in every way- looks, character, personality (loud and bubbly). And I’m wondering now, if he is gazing at these photos and thinking of her.

He told me at the weekend when I tried to speak to him about my insecurities regarding the affair partner that I was being “self destructive”. He said that the photos were for social media and that he took hundreds of everyone on the project. He did say that he should not have gone on and on about her that day after dinner and that I was the most important person in his life.

he also told me I was upsetting him. The thing is all I wanted was reassurance and during the project, and especially the intense last day and all night party I would have thought he could have made a special effort to take a few seconds to say goodnight or to touch base with me. After all, he said twice that he knew this was all hard for me.

The texting has been a real issue but I have never used text before in a relationship so maybe I am over reacting when he takes ages to reply after reading my messages and doesn’t match the tone of my loving messages.

i did think long and hard whether to start this relationship and he was so lovely (and actually comes across as very sweet and slightly awkward which was the opposite of my ex) and i thought he loved me.

my own reactions have surprised me. I get sulky and silent. I want to run away sometimes. He hates this. But it’s hard to talk to him about her and my insecurities (partly because I’m proud and partly because I’m worried how he will react. He tells me when I am upsetting him).

also I feel that if this project had not happened we would have the lovely relationship we had before.

I’m sounding like a pathetic idiot aren’t I?

Your update just makes him sound cruel and you sound utterly miserable.

Please just stop this. I can't see why anyone would remain in such a situation. He is not the man for you (or anyone!).

TwistedWonder · 06/09/2025 10:51

Sorry to be so blunt OP but after reading your update, he sounds like a gaslighting cunt deliberately fuelling your insecurities and then turning full DARVO on you to make it all your fault.

Honestly why would you continue to put yourself through the shit he’s throwing your way? He’s a manipulative lying cheating wanker - please find your self respect and dump the twat.

NZDreaming · 06/09/2025 10:54

@Suneptune it shouldn’t be this hard this soon. Any relationship where your partner doesn’t make you feel loved and secure is doomed to failure. It’s unfair of him to dump so much on you and then accuse you of upsetting him, he is not a nice man. Sounds almost like he’s warning you that he’s able to find someone he feels more interesting should he feel like it to keep you on your toes. It’s one thing to admit past mistakes and be truthful but to subject you to the nitty gritty and then be surprised when you’re upset by it is not on.

You could do with some therapy to unpack your emotions relating to your ex, the betrayal and feeling secure in relationships in the future.

The fact he was repeatedly unfaithful in his marriage is not a great sign for future fidelity and his apparent lack of remorse/guilt is definitely a red flag.

Imbrocator · 06/09/2025 10:58

I’m sorry OP but he sounds awful. Based on his history alone, I’d say leave. If someone has compromised their morals more than once then it’s not a good sign for the future, and your own history means you need someone who doesn’t have this baggage and risk attached to them.

You’ve said a few times that he keeps reassuring you that you’re the most important person, but this sounds like a red flag to me. If he’s telling you verbally you’re the most important, but his actions are the complete opposite, then his words aren’t true.

I really understand your comment about not trusting your instincts. In this case the best thing is to reach out to friends of yours you feel you can trust (hopefully there are friends who supported you after the affair?). Get a sense check from them, but maybe consider some “you time” where you’re not dating anyone, where you give yourself the chance to rebuild your support networks with friends rather than having just your partner who you can trust and ask for advice.

It sounds like you’ve been betrayed by both your life partner and a close friend - that’s going to shatter your trust in people doubly. It takes time to rebuild and you don’t need someone in your life who makes you feel as insecure as this man does.

butterdish93 · 06/09/2025 11:00

After all you have been through you don’t need another man with form for cheating in your life.
please, please end it with him. Being single is better than risking your sanity again. It’s likely that he will do it again as he has in his previous relationships.
you really really don’t need that!

CaroleLandis · 06/09/2025 11:44

It’s not going to work and you need to cut your losses before you drive yourself insane with worry and anxiety.

You will always feel suspicious about him because of his awful track record.

There are plenty of men who do have good morals and he isn’t one of them.

Suneptune · 06/09/2025 11:48

Reading through all of this has been an eye opener for me. Thank you.

I have to got to think about my pride and self respect don’t I. I just sound so whining and petty (texting this, photo that). Though of course it’s not as simple as that.

In the long run though, how do you trust your instincts when there are people out there who are so practised in deceit (my ex husband and possibly this present partner also) and worse, maybe delight in it.

Also re my values, I was thinking it’s not really only about fidelity, but also about not hurting people. I just think that my ex was cruel and so is the present man. And his affair partner. They have all knowingly caused such pain drama and chaos to others (innocent spouses/ children etc) but they don’t care really. And I don’t want to be part of this anymore. I can’t be with someone who is willing to hurt in that way. And I think he won’t care about sticking the knife in me. And the affair partner (who knows about me because he told her) would possibly be delighted that she has such power over me. But I would never hurt others. Just no. And I don’t want there to be power/ control games.Our characters are fundamentally different. Ugh they belong to each other- the eX and this new man and the AP. Like attracts like.

need to make a quiet graceful holding my head high exit. Lick my wounds. Start again.

fall down 9 times, get up 10 as they say.

I didn't need to read all of that to know this man needs dumped. No explanation or arguing, just tell him you are not attracted to him, all the best, byeee.

The only reason to ever give up the bliss of singledom and your peace, to date some bloke, is if he massively enhances your life in every way and makes it all easier and fun.
That's the entire point.
If you find out you're dating some shagger who enjoys lying, is a bit thick, is a misogynist etc.- in the bin.

Life is for enjoying.

It’s not about pride, it’s about choosing peace of mind and yourself over this dickhead.

Trusting your ex doesn’t show poor instincts. His behaviour was deliberately deceitful. His fault.

This new guy could have been spotted as a loser sooner, but you have woken up to him and without too much time/resources wasted, if you end the relationship and cut contact.

Being single is fine and if that’s not your preference long term there are much nicer men!

Mrsttcno1 · 06/09/2025 12:24

Honestly OP nothing that is this hard after only 9 months is 1) worth it or 2) going to get better.

Walk away from this one.

Spot on reply, in my opinion.

This man has got you all twisted up in knots, and his track record is indicative of a weak and selfish person. Far better to be on your own and have peace of mind, I would have thought?

99bottlesofkombucha · 06/09/2025 12:49

I think it is a perfectly reasonable boundary that your partner no longer be friends with women he’s cheated on other partners with. He can do what he wants, but you can say actually I don’t accept this in a relationship. It is not self destructive at all to set some reasonable boundaries, and this man can’t meet them. Ever. He doesn’t even sound nice; tell him it’s not working and you wish him well (I don’t think you should mean that last part- I wish him to get fucked over and heartbroken as that would be karma)

Neemie · 06/09/2025 13:13

He didn’t change his ways after the first round of cheating so why would he have changed now?

Exactly. Once a cheater always a cheater!

Mumlaplomb · 06/09/2025 14:18

Ah OP this is a “when someone shows you who they are, believe them” moment I think for you. He’s told you he is a serial cheat and now is cavorting with an ex lover and rubbing your nose in it. Just bin him off, you’re better than this.
