Hi OP it's scary watching your thread unfold as its about 10 weeks since my life 'collapsed' in an almost identical way.
I found out about my DH's affair with a junior work colleague. We were married 10 years, 3DC, and he was a man nobody would think capable of such a thing. I'm still so shocked, HE did THAT.
I knew and had read about the 'pick me' dance yet still did it and I'm so disappointed with myself.
My DH told me just after Christmas that he didn't love me anymore and it was over, denied another woman. I found the evidence. We had had the most wonderful Christmas. He even shagged 'her' Christmas day after waiting till I fell asleep and all my family had left and sneaking out.
After the big reveal I fell apart for a week, begging on my hands and knees, threatened suicide (I can't believe it, I felt that bad) had sex with him repeatedly to try to 'convince' him I was worthy of him staying and he chose her.
I suddenly came to my senses after about a week and found a house, moved out with the children and have set up the most lovely home with my children. It is a new build townhouse which is actually perfect as it already smelt of new paint and carpets and is perfect for new beginnings.
I went through a phase of anger and sending vitriolic emails and texts but I cannot get him to respond, he will neither explain verbally or in writing what happened or even apologise. He just shrugs his shoulders.
We live in a small town and I have told EVERYONE. Right from the first day I decided not to keep his dirty little secret and I don't think there is anyone left who doesn't know what he has done. His family still talk to me regularly. His father is so sorry and embarrassed about his son's behaviour.
He remains a good father and has the children often. He has given me money and everything I have asked for.
The brilliant news is that I fell out of love with him weeks ago. The scales fell from my eyes and I saw him for what he was, a weak sad little man with a compulsive lying habit. I wouldn't take him back if he was a lottery winner. I write down my feelings and have a 'what I hate about you' book that I write things about him in. To be honest he has been emotionally abusive for years but I never even noticed.
I am now free. I feel happiness and like myself again. I still get down days and moments when I can't believe this happened. Oh and his affair with the OW didn't even last.
This feels like hell at the moment OP but you CAN do this.
