LoserNoMore I've just read all your threads and wanted to say I think you're fucking awesome.
I'm you, a year down the line. I have 3 girls, my STBXH was having an affair with a woman who worked for him (what a bloody cliché eh?)
I found out April last year, he asked to stay and work it out, I reluctantly agreed, we had counselling and all that crap and then I found out in July he was still seeing her - he had her in his phone under a fake bloke's name. I kicked him out in July.
We are in the process of getting divorced, it still hurts like hell sometimes, I find it hard that the man I loved for so long, was married to for 15 years, is a stranger to me. I didn't know him at all.
BUT - I am far happier than I was a year ago, my girls are happier, we are secure, settled, contented and life is sweet.
My ex is still a Grade A twat but he's not really my problem any more 
You are amazing.
