Would his honesty about cheating put you off a promising relationship?

I've recently met a guy online dating, and we really hit it off. First date was just drinks and a chat, and we got on really well. Loads in common, we both laughed loads. Second date we had a picnic at the beach and went swimming in the sea. Definite chemistry - I'm very attracted to him, and he seemed to like me too. Third date he cooked me a meal at his house. Things felt right and I kissed him. It was lovely.

We then spent ages talking about our lives, how we ended up single in our late 40s, and about what is important to us in a relationship. I told him that I'd had a bad experience of being cheated on, and that loyalty was important to me.

I'm not sure what came over me (I'm not usually like this!) but I really wanted to go further and started trying to undress myself and him. But he stopped me, and told me he had been unfaithful to his ex wife during their marriage, and that he couldn't go further without me knowing that, given how important I’d said loyalty was to me.

Obviously that killed the mood. I asked why he'd cheated and he said they'd had no sexual intimacy in years, and he eventually had a bit of a breakdown and slept with someone else. He stayed with her for another ten years after that until his kids had finished school.

I left his house then. And I'm really confused. He was genuinely lovely - funny, good looking, intelligent, kind. Not weird or pervy or anything like most of the guys I've met online. And he didn't have to tell me. But i don't know whether I should move on and wait for someone who has a better track record of being faithful.

OP, everyone is capable of cheating given the right conditions. If his marriage was sexless for years then imo that's extenuating circumstances surely?
Imagine your spouse refuses to have sex with you for years and then you meet someone and you're both really attracted to each other. I'd certainly find it very difficult to turn that down and so would many others.

If you like him, see him again and take it slowly.

Whoever you meet will have a past. Some will be worse than others. The question is whether they’ve learnt from it or not.

His confession seemed to follow on pretty directly from my telling him my views on infidelity. He very much linked his cheating to the extreme and longstanding lack of intimacy combined with not being able to bring himself to leave and no longer live with his kids. He’s obviously a very devoted dad - the walls in his house are covered with photos of his kids and there were photo albums of Disney and loads of other holidays under his coffee table, so it does look like he made “family” his priority. So his story does track.

They all have a story.

My brother in-law always tells women about his past relationship. How volatile they were. How they escalated. How he's worked on himself and had therapy. Then he charms them, manipulates them and BAM they become his next victim. Ive warned them abd been ignored and my husband and I have rescued them.

Did he tell his wife?

The biggest indication of future behaviour is past behaviour.
when someone tells you who they are believe them.

Now, see, if you pursue a relationship with this man and he ends up cheating, he’s likely to see, “It’s not like I didn’t warn you. You knew what you were getting into.”

I'm fairly.pragmatic about these things.

In reality, some people are sexually incontinent. Either because they dont value fidelity and don't consider it important to remain faithful if they see someone who catches their eye, or will actively pursue affairs. These people are the ones who will go through life and relationships cheating without thought or consideration, promise never to do it again and then carry on and hide it better.

Some people through their own moral standpoint will just never do it.

Some people will believe that they're not capable of it and might be right for years but a moment of weakness or vulnerability comes along, or a period of not having safeguarded their relationship carefully, and make an error in judgement or a mistake or just get caught up.on things, deeply regret it and resolve to never let it happen again.

Everyone I know who has ever cheated, fell into the latter group.

My dad had an affair. He left, he married her and they had 20+ years together until he died. He didnt cheat on her. He'd just ben desperately unhappy in his marriage to my mum (for context, my sibling and I are now nc with her and he stayed in the marriage until we were late teens to protect us).

My exh also had an affair. They have now been together for 14 years and I know that he won't have cheated on her because he's not 'a cheater'. But our marriage was in a bad place and my mum's behaviour had a huge impact on us and my dad dying was the final straw for both of us really. It gave us both chance to be happy.

I went out with someone a few years ago who admitted similar to this man has admitted to you. He told me early on, as this man has told you. He was very contrite, had obviously done a huge amount of self reflection, regretted it immensely for the harm it had caused his ex and what it had revealed about him.

We spit up for other reasons but, in some ways, but i was as confident as I could be about anyone that he wouldn't cheat because I could see how it had affected him.

People will say a leopard doesn't change its spots, which is overly simplistic. Lots of people dont realise they could be vulnerable to an affair if they've never been in the position. The people I've detailed above werent in happy relationships. They had been at one point but life had overwhelmed them and they made the wrong choice. Does that make it ok?

No. Of course not. Conversations, splitting up are all far better options but the reality is that humans are flawed and there will even be people who insist they've never had an affair who have done because they can justify why they did it to themselves and so dont consider it in the same league as people who just go out on the pull when they're married or because they dont like what it reveals about themselves.

I also disagree with the 'laying the groundwork' comment. Yes, some people will be telling you 'who they are' (don't give me enough sex and I'll look elsewhere; I'll shag about and when you challenge me on it, I'll tell you that you knew i was like this from the start) and other people will be saying, I was in an untenable situation for a long time. I should have handled it diferently and but I didn't. I made the wrong choice at the time but I regret it and I wouldn't do it again.

There is also a third option: OP holds out for someone who has not already declared himself to be a cheater and actually isnt a cheater. They do exist.

That is true but no one actually knows if they've met this person or the one who has cheated and is lying.

It's a bit of the proof of the pudding is in the eating situation.

Basically, OP, unless someone is communicating generally that they don't value monogamy or is spouting shit about men needing variety or whatever, or is behaving inappropriately with other women when you're out together etc, you have no way of knowing whether someone will cheat on you or even has until/unless you discover an affair.

And someone not having had an affair previously is no guarantee that they won't in the future if the conditions are right.

So you have to judge someone based on what you believe is their position now.

You’re a very wise old owl….this resonates perfectly with me x

I am going to ago against the grain here and say that as someone who was in this almost exact scenario, I would never date someone again who admitted to cheating. I was told fairly early on by an ex that she had cheated on her last girlfriend, I valued her honesty and thought that it was a green flag that she told me, she ended up cheating on me.

My FIL is quite open about cheating on his ex wife, he’s just been caught cheating on his new wife too. Statistically, the biggest indication that someone will cheat on you is if they’ve cheated on someone else.

Well quite. But it doesn't sound like OPs guy is a serial shagger.

I'd give him a chance OP. I have cheated in my much much younger days in my 20s; I woukd NEVER dream of doing so now.

I had similar thoughts until it transpired that your scenario wasn't what happened; he actively went looking for a cheating partner on Ashley Madison.

Which means he reached a point in the marriage where he actively thought, "I'm not getting what I need and can't go on like this. But being married serves me better than not being married, and my wife would be unlikely to agree to open the marriage, so I can either (1) leave and have sex with other people but lose the benefits of being married; (2) stay with integrity, get the benefits of having a wife and family in tact and accept that sex is off the table for now; or (3) get all the benefits of both by lying to my wife and making sure she doesn't know that I have opened the marriage on my end.

And then sat down and deliberately and actively chose option 3.

Morepositivemum · Yesterday 07:22

They weren’t having enough sex so he cheated. Cheating is one of your ‘no’ tick boxes. I absolutely wouldn’t continue. A lot of people are assuming that all/ most men cheat, I think you’re buying into that if you think because he told you it means he’s honest.

That's fairly easily addressed by just talking about it though. You can remove all possibility of plausible deniability through an up front conversation.

I missed that detail.

I don't know much about Ashley madison but maybe he though no strings sex where both people were married but not planning to divorce was better than a typical affair? 🤷‍♀️

TBH it's difficult to say without knowing him/his ex wife etc and all the details.

Frillysweetpea · Yesterday 08:15

I have never been cheated on, to my knowledge, so I might not be best placed to judge, but I would value his honesty. Plus I have some sympathy for anyone who feels emotionally and sexually sidelined in a relationship. It seems to me to it was an infidelity of a different nature from that of bloke who is serially unfaithful whilst still having sex with his partner who believes the relationship is happy. I get the feeling this man would commit if the lines of communication are kept strong and healthy - that seems to be what he wants from his behaviour so far. Hope I am not being naive but in your shoes I would go for it.

Yes, there were a lot of ACTIVE, deliberate decisions there. All fueled by rampant self-pity and entitlement that allowed him to tell himself he "deserved" to cheat.

And he STILL has that self-pity and entitlement.

He had options: counseling, talking to his wife, leaving. But no, the poor poor man, he HAD to cheat.

lottiegarbanzo · Yesterday 09:13

I’d be asking him what happened when he talked to his wife about their relationship, what he discovered about why she’d lost interest, what work he did to restore it, what they did together to improve things, what her priorities and preferences were - in her own words, not his assumptions.

Did she agree to the ‘stay together for the children’ plan, or would she rather have split earlier, giving them both a chance to find someone more suitable, or build a peacefully single life?

Did he truly see her as a person with her own needs, experiences, priorities, preferences? Or as a provider of services who had failed to deliver one of these to him, thus breaking their contract and giving him permission to fulfil that need elsewhere?

…While still drawing upon all her other domestic services and failing to tell her their contract had been nullified. Without his having to take any responsibility for uncomfortable communication or effort within a messy human relationship.

Person or service provider is the conversation I’d be pursuing. Transaction or exploration? Selfishness or sharing? Safe or unpredictable? What are relationships about, to him?

You’re late 40s you’ll be going through the menopause soon, if you haven’t already. Your sex drive will change, may disappear and you’ll experience other symptoms. Are you looking for a fun fling for as long as your libido lasts, or someone you might want to spend the rest of your life with?

Just had a message from him:

”Hi, I thought I’d follow up on Sunday night. I really enjoyed seeing you again, and would love to have a fourth date.

I know conversation got a bit intense at the end of our last one, and I will completely understand if you decide you’d rather move on than take a risk on me. I’d be very sad not to see you again, but I’m glad I was honest with you regardless.”

I hadn’t contacted him since our date due to not knowing how to proceed! I’ll need to make my mind up soon - I hate ghosters and don’t want to be one!

Honestly, this whole thing has pinged my bullshit radar hard.

Him telling you about his cheating sounds like a ploy to get you keen and get past your boundary. It's called tactical vulnerability: by voluntarily bringing up his past cheating and saying it was a single mistake, he created the illusion that he is transparent, a moral strong man, and his morals are stronger than his desire fort sex. He's got you thinking, "If he's willing to admit something this bad, he must be honest and trustworthy now."

He certainly got many people on this forum believing that, which is understandable because most people are kind and honest and inclined to give others a chance.

Next he gives you a low-ball nudge with a message intended to trigger certain psychological reactions:

-"I will completely understand if you decide you’d rather move on" - this relieves pressure on the surface, which lowers your guard.

-"take a risk on me" - this intends to make you feel guilty for walking away because it'll make him "sad" (women are highly suggestible to this crap). You'll feel like you shouldn't walk away because then you're punishing him for being honest.

-"I'm glad I was honest with you regardless" - again, he suggests his honesty should be rewarded with another chance.

I think you're being played, OP. If your bullshit meter is pinging, as mine is, trust it.

At best, you are selecting against men who tell the truth. At worst, you are actively training men that they should lie.

I wanted to come back to this because there's something really off about it.

Men who lie to get what they want are responsible for those lies. Not women.

Women are blamed for everything that men do or don't do. I suppose now it's also our fault that men lack the moral compass that stops them from lying.

thisismeithinkorisit · Yesterday 09:31

did you message him back @SmoothandFluffy?

personally I would think that the time period since it happened (he stated for over a decade more and it's been how many years since?) and his honesty at a point when he gave up guaranteed sex would be points towards seeing him again.

I think the key difference at your age is he could just walk away if he was unhappy. I understand why many people, but especially men, don't feel that's doable with young kids at home.
should he have cheated? no. does that mean he must have continued to cheat for the next decade and be cheating on every woman since? also no.

i'd give the 4th date a go.

I would have left the ball in her court.

She told him she had a boundary. He told her he had crossed it "once". She left to go and think about it.

He should have waited for her to get back to him. That's respectful, also of her boundary. Instead, he piled on some guilt-inducing emotive crap.

This guy is pushy and likely a player.

SmoothandFluffy · Yesterday 09:38

Thanks everyone for your input on this - I can believe what a massive divide there is in people’s views!

It does seem that most (but not all) of the “don’t touch him with a barge pole” answers are using a lot of loaded language, are making a lot of big assumptions about him which don’t seem to be based on anything, and applying very black and white thinking. Some of the recent ones have even started suggesting his up front honesty and “niceness” is part of some kind of evil plan to manipulate me, which really stretches credulity.

In contrast the “take a chance but maybe be careful” responses seem much less loaded, and lack any extremist feminist undertones.

I had a phone call with him last night and gave him a grilling. Again, he could be lying, but he said that they had had lots of counselling and sex therapy with no result - and in the end she just said there would be no more sex/kissing or anything along those lines again. She’d begged him not to leave and said she couldn’t cope without him due to her mental health problems, and refused his request for an open marriage. He had a breakdown and chested, felt guilty and then threw himself into family life until his kids were starting to leave home and he started feeling lonely again. Then he left.

I’m actually not going to see him again, but not because of the cheating. I’m not going to see him again because I just don’t want to have to deal with someone that broken, which reading between the lines I think he probably is. I feel desperately sorry for him, and I think he would have been a lovely partner under different circumstances. Hopefully he will find the right partner, but unfortunately it won’t be me (there are reasons I’m not equipped to be the supportive partner at this stage in my life, but I don’t want to get into that).
