I’m in my 50’s so like to think I have a bit of life experience. Over the years I’ve seen a variety of men cheat on their wives/ling term partners. Ultimately, just because they could. They didn’t get going out and stayed together. Or maybe they did - who knows?

fasg forward a few years and these men are now in their 50’s/60’s and their wife/partner that they’ve been with for years, and who they treated so loosely when they were younger, is now their EVERYTHING.

Ive seen this quite a bit. Why is this? Have they finally grown up and now see what they’ve always had? Do they have regrets? What’s it all about out? Anyone else seen this?

I snorted at this

Yes they do mature more slowly but really, do they only reach full maturity at 60 😂😂

Definitely. I see this in my ex. He's a much more reasonable person than when we were married. He was a fucking idiot when he was younger.

Youlittlenightmare · 15/04/2026 22:56

Right. This is it exactly. They are no longer appealing to most women, they age, they are afraid of dying alone and infirmity. That's it. If they were suddenly chronologically younger they'd start the whole sad, grubby merry go round again.

Unfortunately for his current wife, that parcel does not unwrap to reveal a prize.

Very true but don’t feel too sorry for her because she was my best friend and was having an affair with him for a year before I eventually found out by pure chance on seeing photos of them inadvertently stored by his phone on our home computer!

I think they deserve each other.

firstofallimadelight · 16/04/2026 05:24

Yes I’ve seen this too. I assumed it was lack of opportunity due to aging/less desirable. It could be the wife prepares to leave which shocks them into realising that they actually need her or a significant life event helps them realise what they have.
Or literally that they finally grow up and realise they need to stop messing around.

I have two serial philanderers in my family and they're still at it in their early sixties. One recently admitted to me that he never felt any guilt about cheating on his ex-wife, who he was with for forty years and is the mother of his kids.

Just because they make out that their long-term partners are "their everything" (barf) doesn't mean it's true.

I think being unfaithful is a personality trait. A very stable one.

Nowvoyager99 · 15/04/2026 08:07

Really? I am in my sixties and see the opposite.

These men have perfected their “my wife and family are my world” pretence and carry on fucking anyone they can.

This.

I just love the way the guys that have posted here are saying it's 'maturity'.
Lol.

To be fair, I do actually know of one serial cheat who I think reigned it in when his children were born.
He was still attractive but as his father cheated on his mother and he saw him and OW kissing he really did seem to be adamant he wouldn't cheat when his kids were born.
He was a bit of a joker but I did get the impression he was deadly serious about this.

I think it's totally shitty that love for his partner wasn't enough for him to rein it in.

I'm friends with a couple like this. What changed him was religion and realising how wonderful his wife is. She can now do no wrong. He is still rich handsome in his 60's and would still attract attention, I would say.

He found religion?? Bloody hell, I've heard some BS in my life, but this takes the cake. He's probably shagging half the congregation!

jellyfish798 · 16/04/2026 05:59

My uncle is an example. Realises he has alienated his son (cheated on his mum) and knows he won't look after him in his old age. It's not that he's become a good person. His new partner is also wadded so he will have a comfortable retirement if he plays his cards right.

Rounder888 · 16/04/2026 06:24

My FIL was like this. Ran off to work abroad and left his first wife and kids. Then with my MIL preferred going to the pub and chatting up woman, or going on holidays to Thailand (yuck) however, now he’s gotten older, his back and legs have gone so can’t go dancing on a Friday, got stomach issue so can’t drink, and has to eat a specialist diet which he struggles cooking. He is full of regret now about how he treated my MIL, and generally feels sorry for himself. Also wonders why his kids don’t really bother to see him much

Boomer55 · 15/04/2026 08:31

It could be they've just found the right’ person and no longer want to cheat.🤷‍♀️

I think OP means that they're still with the person they cheated on.

With my dad, it seemed like he became grateful for family life, to be included in adult children and grandchildren lives and grateful to my mum for staying with him.

My partner was like this with his first ex and his ex wife. With his first ex he used to visit brothels, disappear on lads holidays, stay out for days. Had numerous affairs with her friends etc. Wasn’t around for the kids. They split up (she cheated in the end).. He then met and married his ex wife. No kids but more of the same. We’ve been together on and off for years (during breaks from partners when younger). Solidly together for 9 years and have a child. He’s never stepped out of line. No disappearing out with his mates, sneaking about nothing. He helps with our son and is very present (like under my bloody feet present!). Both these exes absolutely hate me for it!!! Have asked why he’s so different with me. He told them honestly he never felt settled with them or as close to them!! And we can be swinging from chandeliers occasionally so it’s nothing to do with a dwindling sex drive. Don’t get me wrong, things aren’t perfect. But he’s like a different man with me and our family. I just think when someone’s genuinely happy they are happy. Now, to find ways to make him bugger off on a lads jolly to give me some peace!!! lol!!!

Why did you entertain a man who believes he can buy consent while putting his loved ones (mother of his children and possibly his children) at risk of life altering diseases?

If I was on a date and found this out I’d leave the restaurant/pub/place immediately. I’d say oh I need the loo. I’d settle my bill and exit without saying a word. As he wouldn’t be worth my time.

He believes you can buy consent with cash. A significant amount of prostitutes have been abused as kids or trafficked. Yet he believes a wad of cash means they have to let him orgasm. Touching him would make my skin crawl.

What attracted you to him?

As my DF told me ‘all of a sudden, we are no longer to cool funny men who can get away with being cheeky, but we are considered to be the dirty old man.’

ChaToilLeam · 16/04/2026 06:35

They realise which side their ageing bread is buttered on.

Acutissima · 16/04/2026 06:42

The parasites move from host to host, until their lifespan is almost up, then they are left with no option but to attach themselves to one host where the conditions are favourable to continue sucking blood until the host dies, or they die first and the host is freed up to live without being drained.

Their most favoured type of host, after all the younger ones have dried up, is a "nurse with a purse".

No, it is common knowledge that while opinions, beliefs, and politics may shift, moral character traits display substantial long term stability. Early tendencies toward dishonesty or betrayal are very meaningful indicators of future conduct, and these patterns commonly persist.

Lifespan longitudinal research shows that core dispositional tendencies are meaningfullly stable from adolescence into older age, meaning early patterns of dishonesty, exploitation and betrayal remain informative about later moral conduct across the life course.

I mean, we all know this anyway and it is common sense but there is also research to back it: "There also appears to be substantial stability of individual differences in personality, even over several decades” “personality changes only gradually throughout life” pmc.ncbi.nlm.nih.gov/articles/PMC5144810/

In other words, the best indicator of future behaviour is past behaviour - and that is a truism simply because it is true.

And so, since the risk is very real that entitled, cheating, lying, treacherous people remain so throughout their life it is safest to avoid intimate relationships with such people if you know about their past conduct.

Yes!!

Transpires the cheating - now- no- longer- attractive ex who thought he could do better than me but hinted he wanted to get back together in his middle years, had told a massive lie to his mother about something quite serious for his own personal gain and was also exploitative of the single mum he moved in with who later chucked him out.

I like this post: confirms what I suspected: people usually have change foisted upon them, rather than an active choice.
In this case, his essential character was the same but he couldn't be that way any more.

If I had been dumb enough to get him to a good place: fitter, better etc than no doubt I'd be rewarded with him cheating or thinking he could do better again.

So glad I blocked and deleted him.

My dh and I have had issues - like any longstanding couple - but honestly I give anybody permission to shoot me if I'd left him for this twerp.

Nah, he's genuinely sorry (admitted that his family had been dismissive of his DW and he had been too) and the non denominational congregation is mostly made up of elderly people. He also donates a good percentage of his income to charity.

I honestly don't think it's BS.

I think being unfaithful is a personality trait. A very stable one.

Right, research and common sense and basic human experience backs this up.

Cheating takes the sort of person who is quite willing and able to lie persistently and repeatedly to a person who loves and trusts them as well as being willing to put their sexual health at risk.

It shows a deeply unethical character and low morals. It shows a true contempt for the person who loves and trust's them basic rights.

This is not a case of a kid swiping a chocolate bar in the supermarket and it's not a "mistake". It actually takes a certain lack of empathy, kindness, consideration, normal human feeling, it takes a cold hearted, unkind, entitled and unethical person to cheat.

And it's not normal. 4o out of 5 men do NOT cheat, and women cheat even less. Something like 20 percent of men do cheat and 13 percent of women. NOT the majority, and not actually normal.

That tallies with what we know about people. If we lived in a society of lying, abusing cheaters where treachery was normal we would be well and truly fucked.

Cheaters have done a great job of making everyone think betraying your partner is normal and try very hard indeed to minimise how loathesome cheating is.

But they are very much in the minority, it's not normal to treat someone like they just do not matter and have no rights and as such because it is an abnormal trait, it goes deeply to character. It's not naughty or even bad behaviour - it is a character trait. The people who cheat are untrustworthy in their very core.

And we all being sly, unethical, unkind, low empathy and entitled doesn't suddenly shift because you get older. You don't meet someone who is lacking in compassion and ethics at age 25 who suddenly becomes empathetic and ethical aged 50 - that would be vanishingly rare.

So yep, cheaters are stable in their low morals and ethics, and it would be dangerous to stake your happiness on them being the rare one that breaks the mould.

Honestly, the older I get, the more I think we’re all just prisoners of biology as @jsku says. Society has imposed norms but we’re wired by survival instincts to behave contrary to that at the most basic level. Older men shag around less than younger men due to less urge and less opportunity.

its kind of like the old narrative about weight loss. “ You need to address the real reasons you overeat” ( subtext: there are complicated emotional reasons for your obesity). No you don’t. It was never that deep. You just need to take this jab which adjusts your hormones and overrides your primeval urge to eat all the food while it’s available so you don’t die in the next famine.

Older men shag around less than younger men due to less urge and less opportunity.

Agreed. Note less than before, not never. And the few with both vitality and money shag around as much as younger men with fewer privileges.

Source: like @ClaredeBear, family history. And dozens of long-standing male friends. The only ones who don't shag about in later life either didn't when younger, or have lost the ability.

GrannyAchingsShepherdsHut · 14/04/2026 22:30

They don't change.

They just either don't have the opportunity to cheat because no one else is interested in them, or they are still cheating, but just got better at covering it up.

This x 100. Cheaters rarely stop cheating, especially if they are still with the same long term partners .
More likely they hide it better or are just having a fallow period

I always wonder if people who think this way have themselves never changed their ideas or behaviour as they have become older?

I have! This is because I'm now chronically ill and chronically poor, though. Actually, just the ill part - if I were broke and old but healthy, I'd still be finding ways.

Am single, btw. Just answering the question you asked.

Considering that most people get better off and more free time as they get older, the options for hiding one's personal activities expand significantly. Overseas cycling tour, golf weekend at beautiful resort, day-rate room at discreet hotel, volunteer activity, soooo many hobbies!
