To think about ending a 30 year relationship?

Sorry in advance for the lengthy post.

I’m wondering whether to leave my partner after nearly 30 years. We’re not married but have two teens. We didn’t get married because, for a significant period of our relationship, quite some time ago, before our now teens came along, she was unfaithful with a number of ONS’s and casual flings. I didn’t know about them until they’d been going on for about 5 years.

To her credit, she tells me that she’s told me everything (there was a lot to tell), and that she did so because she wanted to commit to me, she even proposed more than once. They were pretty disgusting by anyone’s standards, both in number and nature. Try as I have to get over it, it’s always been there bubbling under the surface and most of the time I’m fighting with myself not to show my resentment.

Domestically and as a parent she’s incredible, wonder-woman incarnate. She’s good company and we share interests, political ideology etc. Our sex life’s never been straightforward. A ‘complication’ very early in the relationship all but killed it off for a few years, and when we did recover it was fraught with anxieties. Although post the infidelity we worked on it with couples counselling, therapy etc, I can’t help but think it’s never been quite as it should. She would say otherwise, that we/I do enough for her to be happy, but I’m not. It’s more often than not one way, me meeting her demands for attention, meeting her desires when she's in the mood, and me getting little to nothing in return, quite literally. She makes little to no effort with or for me. I get shut down if I mention anything remotely related to sex in any context unless she’s asking me to tell her fantasy stories and ‘satisfy’ her. It's always on her terms.

I’m mid 50’s now and want some of that attention, and frankly some fun before I’m too old. I’ve thought about separating before but financially it wasn’t possible and the kids too young. But I recently inherited a property and keep thinking is this the right time and circumstances to leave? Despite my hurt and resentment, I don’t wish her any ill will at all, in fact I love her and our kids very much, but I can never feel like I did before her infidelity came out. It changed me a lot. I’ve been a miserable old trout for 18 years, whereas before I was, and was known, for being sociable, laid back, unargumentative and devoted. I showered her with attention and put her on a pedestal. But I want my old self back before it’s too late.

Yes leave and enjoy life without her, you were foolish to stay when her shagging around came out.

100% get out OP, you’ve more than given this relationship a fair chance and you deserve to be happy

Perhaps you could have rescued it with therapy and effort at the time, but it sounds like you’ve sat on resentment for decades. Perhaps therapy would be worth a shot before ending it? The grass isn’t always greener on the other side.

Cheating destroys relationships. Always. Sometimes a weaker, poorer version of the original relationship can grow from the poisoned corpse of the original relationship, but the original relationship is always destroyed. And the new version is never stronger, never better, never quite clean, never as good and always tainted.

Cheating is abuse of the worst kind. Horribly cruel, it utterly changes the world for you. The person you would normally turn to in your despair is the one who tortured you, that is a total mind fuck. And you look at every memory with a jaundiced eye, knowing they were lying to you all along. It makes you question if anybody is ever trustworthy.

I'm sorry she did that to you. It's a horrible way for her to choose to behave.

You'll always get abusive cheaters trying to minimise and find a way to blame you for being a victim of abuse. Ignore them. It's about them, not about the truth or about you.

I think you should go and do what you want to do. But see a lawyer and get your ducks in a row first.

Yes, I’d leave. You have built up patterns and habits that will be impossible to break. You may not meet anyone new, but living with this resentment is no good for you. At least give yourself a chance to be happy.

Financially - I hope you arent envisaging “falling on your sword” and letting her keep everything - are you going to be impoverished ie does she own your home?

Dude.
We are similar in age and length of a "bad" relationship. I also have 2 kids 15 and 10. I personally don't ever want to be in another relationship and I just want to break out and have peace with silence. Are you looking forward to having another relationship?

Thanks for your post.

No, I don't really have any intention of being in a relationship again, at least not one where we end up living together. I crave my own place/space now. I want that more than anything, and then the chance to rediscover my sociable side but I'll never throw myself head first into a full on relationship again.
