I am so sorry you are going through this.
You are absolutly right about him being sorry he got caught. That is exactly how my wife was when I found out about her affair.
I felt at times numb, then full of rage and then just broken. Sometimes all of those plus more in the space of minutes.
My self worth took a nose dive. I can honestly say it was the single worst experience ever. And it does not go away.
It does lessen. The random flashes of thoughts lessen too.
But it never goes. Or at least not yet.
We did stay together but only after a severe turning point for my wife when she stopped being sorry she got caught and was genuinely sorry for her actions. There is a huge difference.
Since then she has done everything she can to reasure me even to her own detriment. She has stopped going out with friends unless I am there too. Not because she doesnt trust herself and certainty not because of anything i have said. She worries that I will worry. And there is little I can do to convince her otherwise.
I made no demands. I gave no ultimatums. There were no rules set by me. I was just too broken, I thought i had no idea before. What makes me think any rule or boundary would be followed unless im with her 100% of the time. So either I trust or I don't.
I knew the pain a second time would cause and weighed up my feelings for her against that and decided it was worth the risk. But not while she was only sorry she got caught.
After that shift and change. Everything opened up. There was no holding back on information or dodging questions. There was no attempts at changing blame even slightly.
Before the shift my wife didn't want anyone to know especially her closest friend. But after she was accepting of what people would think of her.
We still chose who to tell. My MIL will never know because she likes to make barbed comments and can be very hurtful and insensitive. My sister will never know as she would stick her oar in and try to cause drama.
Our best friends do know as I needed their support and as it turns out so did my wife.
We chose to tell people who would not decide what had to be done. As no one knows except you.
Before all of this I was very set on any cheating of any kind was the end. Unacceptable and totally unforgivable.
That went out the window within seconds of finding a pregnancy test that couldn't have been because of me. When faced with absolute proof not long after all my convictions were gone and I just felt numb. I think at that time had I of confided in someone who would have told me what to do I may have followed their advice. Luckily I confided in a friend and through him his new girlfriend who was an old old girlfriend of mine. There advice was only on how to breath and keep going. Not once did they say how I should feel or what I should do. They just let me know that they would stand with me whatever happens.
Find yourself people like that.
Sorry it got a bit long. I struggle to write short things.
Best of wishes. And remember. None of this is your fault. You are not to blame. Dont let the doubt creep in.
