I’m cheating what to do

Hi all. For the last couple of years I have realised fallen out of love with my DH. We’ve been married for twenty five years and got married in our late teens and we both came from religious households (I am no longer religious myself). We have three children together (19, 17, and 16). I don’t hate him but I just no longer can stand being around him. I am ashamed but for the last nine months I have been having an affair. He’s not in a relationship and he is generous and kind. He says now that I have to tell my husband about us so that we can officially get together but this would mean admitting to what I’ve done. I don’t know my children or parents would react to me having done something so horrible. What should I do?

We actually met at the gym. My husband never goes to the gym so that’s where we kept meeting up.

Fgs stop cheating on him you met at the gym 🤮

Stop?

The kids deserve to know what their mum is like and what she has done

What their mum is like and what she has done? Oh you mean, birth them, raise them, stay with their very probable lump of clay of a father despite being soul suckingly unhappy so they could have a decent childhood? You mean that?

This isn't the place to ask OP. Just do what causes the minimum hurt. It sounds like you're planning to end the relationship soon anyway so the cheating is fairly irrelevant and you don't need to announce it to the whole world. You don't need to walk on your knees for 100 miles through the desert repenting. These things happen.

Absolutely agree with this 10 000%

PollyBell · 16/01/2026 02:29

If you are not doing anything wrong then you have no reason not to tell everyone, if you cared about your children you would have left your husband first then had a normal relationship

If you use the old cliche 'I am not cheating on my children just my husband' then there would be no reason to not to tell the children

So if you tell people now and who will live where? will you have to uproot your children, whether you stop it or now your marriage appears to be over so mabe try and put your children first?

I'm clearly going to the wrong gym. The blokes at mine are either students, gym bros who can't tear their eyes away from their own reflections, or OAPs.
😕

Mine is mostly just pairs of roided up gay men, in pairs, yelling encouragement at each other lmao

Onthemaintrunkline · 16/01/2026 03:08

You’re another who wants their cake and eat it as well. You sneak around enjoying the attention from this other bloke yet fearful of your parents reaction! As if their opinion and reaction is more important than your husband’s and children!

You are right to feel ashamed. Leave your husband, ditch this new squeeze and spend time alone, you need time to set new moral boundaries, as presently you do not appear to have any.

21secondstopassthemic · 16/01/2026 03:12

Lucky OP! I need to up my game and stop looking like Miss Trunchbull at the gym, none of the hot guys there ever approach me!

This is one of the worst examples of moral and logical reasoning I have seen on Mumsnet. She knows she is doing something 'wrong'. That doesn't mean the entire world needs to know about it. Ever done anything wrong yourself? Want everyone including your children to know? Let me guess. you're little Miss Perfect and you are an open book blah blah blah. Well, at least she isn't boring.

DeepRubySwan · 16/01/2026 05:02

Thank God people like you don't run the world or we would still be burning people at the stake in public. If you have nothing constructive to contribute, please f off.

No I cant say I have cheated on my husband, as rare as that appears to be by your thinking, if that makes me perfect than so be it I can still sleep at night

Elektra1 · 16/01/2026 05:45

What to do? Stop cheating. It doesn’t end well, ever.

HadAnAffairOnce · 16/01/2026 05:45

OP from one who’s been there and done it in identical circumstances - end the affair, end your marriage, be alone and then see where it takes you.

Do NOT tell your husband about the affair because your affair partner told you to. He is unlikely to be the person you think he is.

My world imploded when I did exactly that and the hurt and damage I did to my ex husband and children still haunts me.

I learned valuable lessons from this and 6 years later I choose to still be single.

I am fortunate that my exH and I are good friends now after some turbulent years, he completely accepts his part in how bad our marriage had become, how utterly miserable and downtrodden I felt and why I felt trapped and had my, as he put it, “head turned”. He did actually say he just wished it had been with someone worthwhile rather than the absolute narcissistic asshole that it was!

My children were adult and then 16 and 18 and I am only now in the last 12 months actually in a good place with them. They were incredibly angry with me very blinkered as to how unhappy I was as we kept the state of our marriage quiet from them but the fact I had an affair is unforgivable in their eyes.

There is no excuse for an affair if I could turn the clock back I would have found a way to end the marriage and definitely definitely not had an affair.

I am one of those rare people that would never ever ever do it again and actually cannot believe that I did it. To this day, my exH blames the menopause - It was certainly the most out of character thing I’ve ever done in my life!

Whatever the reason for me doing it, I don’t know. I am normally a very family orientated homebody who loves nothing more than taking care of people..

That got very long what I’m trying to say is - Nice people sometimes do shit things and please follow the simple advice I said in my first paragraph.

HomeTheatreSystem · 16/01/2026 06:20

You have to think about this as if the affair partner were not in the mix, would you still be taking steps to end your marriage which clearly died a while ago now? You've not known this new man all that long and you certainly don't yet know him well enough to be sure that your relationship with him will be a successful one. If you disclose the affair to him or your parents, it will be used as a stick to beat you with on religious grounds and guilt you into staying in the marriage which would soon become hellish for all of you, especially the children so if you can keep it quiet I would. The core truth is your marriage is over, affair or not. I would end the affair and the marriage. If the AP is genuinely a good man and in it for the long run, he'll wait it out until you're free and ready to start afresh.

Globules · 16/01/2026 06:29

First things first. Do you want your marriage to end? Do you want to go to counselling and try to find the love you once had for your husband or are you done?

If you do want your marriage to end, do you want it to end because you want to be with the new man? As that's not a given. You don't have to be with him if you don't want to.

But the new man has made you realise you need to make some very hard decisions, and there will be horrible fall out to whatever decision you make. But the time has come to decide. Only you know what you need to do to move forward.

All the best.

Makingadecision · 16/01/2026 06:48

Of course he’s nice and generous. He’s not living with you and three children. He’s not known you for 20plus years. It won’t last and you will have ruined everyone’s life including your own. Stop the affair

FrodisCapering · 15/01/2026 14:02

The morality police are out in force, OP.
Do what seems right. You only get one life.

That’s right she does only have one life and so does her husband, so she needs to stop being a coward and own up to her husband about what she has done and let him know what is going on in his marriage.

OP grow a spine, do your husband a favour, have a little bit of respect for him and tell him what you’ve done, then go find some respect for yourself. Imagine having someone in your life for 25 years and cheating on them. If you didn’t love you husband then bloody well leave, he at least deserves that. If you didn’t want people to know you were cheating then you shouldn’t have cheated in the first.

No I don't think her husband deserves it, what i do think is creeps hanging round gyms hitting on married women will probably do it again and again. They like the thrill of the chase, the excitement of the lies and deceit. Once its official they'll both get bored, will 'fall out of love' and be on to the next fling.

Yeah but you don't know that, maybe she hit on him? did all the running?

If he has hung around for this amount of time, maybe he'll be a keeper, most men who hit on married women, move on once they get a shag.

Sometimes people marry the wrong person and then find love elsewhere but so long as she stays in this loveless marriage, she'll never know for sure.

TheIrritatingGentleman · 16/01/2026 17:09

Obviously you know you've done wrong, but I don't see what good can come of you telling everyone you're a cheat.

Yeah, you'll get what you deserve when everyone is angry at you, but your husband will likely be even more devastated and your children may stop talking to you. I don't see how it is the best thing for them to know their mum, who presumably they trust, could be so deceitful.

Separate, yes. Then take some time on your own to see what it is you actually want.

I understand the AP wanting you to separate so you can be together, but I don;t know why he thinks the best thing is to tell your family about what the pair of you have been up to. Surely he knows you are going to hurt your children and husband? I would think twice about whether he's actually as nice as you think he is.

ashamedclown · 15/01/2026 20:05

Read again, she says I know I have done wrong. And I do.

The ability to use the question mark key doesn’t make you superior to me; I know what I have done is terrible.

I don't think all the family has to know about your affair - that's your call and your call alone.

MartySupremeisascream · 16/01/2026 22:32

dadtoateen · 15/01/2026 21:26

Would you think like that if it were you in her situation?
Somehow I doubt it.
I've known a lot of male colleagues who had flings and none seemed to lose any sleep over it and most are still with their other half so most likely kept their mouth shut. Men have a habit of holding women to higher standards than they hold themselves.
