Exit my story is similar.
Almost 4 yrs ago I found out by accident that my husband had been having an affair for 6 yrs. It was mostly emotional (long distance as we had moved a couple of times over the course of it) but as many snatched weekends etc as they could manage.
For us, it was much the same as you - we had grown apart due to having kids and life getting in the way, I was lonely (he wasn't, he had an adoring sap on tap who hung around for 6 yrs believing the shit he was spinning).
When I found out, it was like something that had been eluding me had clicked into place,and I realised that I had always known in some way, I had just been utterly blind to it.
I made him phone her in front of me and tell her I knew, and that he was finishing with her.
I kicked him out then and there and said I wanted one thing from him which he owed me, and that was that he wouldn't run off to hers (we lived within an hour away again by that point), and he wouldn't contact her - not until we had had a chance to talk ourselves without the kids there.
He agreed and did just that; the next 3 or 4 days we talked and shouted and dug up every sordid thing (weekends away, unexplained late nights etc - that's when I realised I had always really known, somewhere deep down, tbh).
The OW grew increasingly hysterical and nasty over the following week of no contact, and deployed every manipulative trick in the book - including phoning me to tell me every shitty little detail and to tell me that every time he had left me, he only went back because of the kids (he had never left me once btw, that was the lies he had told her, the lies go two ways), I told her he'd never left me once, and that I had kicked him out and she was welcome to him, she had 'won' her prize, I didn't want him.
This sent her over the edge as he had been no contact with her, so he had made his priorities known at that point as far as I was concerned - he had been honest with me for the first time in 6 yrs (re the no contact).
Over the next month we talked more honestly than we ever had, about everything - the mutual unhappiness and loneliness within the marriage, what had gone wrong and when, and I consistently shut down any notion that he was not entirely responsible for his own penis; I was hard-lined about the fact that he was responsible for his own actions, no one forced him into anything; he had made choices and he had to own them.
I told him that there were 3 choices,and only he could make the choice:
- He wanted to be with OW
- He wanted to be with me
- He wanted to separate and be single
I promised that I wouldn't use the kids as a weapon and he would have joint custody etc, and I would keep things as amicable as poss if he chose to leave; I also told him that if he chose me, he would have to prove himself and I would make my choice as to whether I wanted him when I was ready - and I could not guarantee that I wanted him.
He chose me, and spent the next 6 months doing what he should have been doing for the previous 6 yrs - putting me and the kids first, and giving us 100% of his attention and energy.
After 6 months I agreed to try again, and we started marriage counselling - it was tough but we were both brutally honest with each other, which was key I think.
Anyway, as with a pp, we are now nearly 4 yrs on and we are still together. It is a different marriage to before, but it is good - it is better I think - I understand how he ticks and he does me, more than we ever did previously.
The affair is something that happened, but it doesn't define things - it was a convenient 'out' for a selfish man who valued his feelings and needs above those of his wife and children; an available woman, who was willing to devote all her energies toward pandering his ego made it possibe - if it wasn't her, it would have been someone else.
It is all so predictable, boring and tedious - yet it causes actual physical pain to the people it affects, and the mental & emotional battering are horrendous.
All I can offer you is my story,
, and my sympathy and empathy.
You will do whatever is right for you, and you will regain your old self - it will all come right eventually for you, whether together with or separate from your husband.
This is not a reflection of you, you did not cause it; he alone is responsible for his shitty actions, (and similarly the OW is responsible for her actions, she is a grown woman who knew what she was doing too - she did not make him do anything, but at the same time she was a willing participant in deceit).
Whatever happens, my thoughts are with you - best of luck with whatever you decide to do. You have the power now, you dictate the outcome.
