My husband and I decided to separate last July after 23 yrs together. Our marriage started going wrong when we had our first child 11yrs ago and had been gradually getting worse over the last 5 years. We limped on but ultimately decided to separate. My only regret was not doing it sooner.
I'm in the happiest place I've been in a very very long time. The children seem fine, seeing their dad every weekend and a couple of times in the week too. I'm having the most wonderful time, I'm relaxed, I've met a guy, I'm going out having fun, all good.
The thing that still taps at my brain is my husbands EAs. 3 times since the children were born I've 'found' explicit texts/facebook messages to other women. The first 2 times I chose to forgive, the last one I found just after we'd decided to separate but it had been going on for 'long enough' (his words)
The messages were enough for me to accept that he'd been having affairs, they clearly showed that he'd spoken with these women many times, if not met them. When confronted he denied doing anything physical, and therefore didn't think he was doing anything wrong. He said he hadn't slept with them.
By the law of averages I know that if these were just the ones I caught him out on, the chances are there was much more going on that I never found out about. In my head I've decided that he must have slept with them all, and there was probably more women.
But he'd never ever admit it. So I should just draw a line now and forget it, so why do I feel the need to find out definitely what went on? I want him to finally admit he was unfaithful, and then I want to go and tell everyone. Then I want to tell him I've met a new man and I'm deliriously happy. (I know he won't like that, it'll be my revenge) Stupid, and not very respectful to my new man 
Why do I want to do that? I'm not 15, I'm 39. I'm a sensible person. I've been through the separation and come out smiling. But I can't quite move on past this. I think it's because it feels like much of my marriage was based on lies and I now need to know the truth. Any advice to forget and move on?
