So after years of thinking that he'd been cheating (found a phone bill 2 years ago when children were really small 1 and a half and six months old) that has numerous calls to escorts on it. I confronted him at the time and he said he had never gone through with it. Then a year ago I found a mail from a woman he know who had sent him a photo of her pool in holiday- he had responded to say 'where are the naked photos of you'. Again I confronted him and he said it was just harmless banter. Finally a week ago I found texts from a woman who he has been sleeping with- this time he couldn't deny it. Anyway after being a bit quiet for a while he says he has nothing to be sorry for- it is all my fault for not giving him enough attention and for being mentally not right (there is no grounding for this, apart from a short bout of depression after my second child- I have a full time job and have full responsibility for the children while he is away at work during the week). He also says I can get out, but if I try to take the children with me he will have them back. I moved when I had my first child, so have a limited network and no family here. His family are all here and he tells me regularly that they can't stand me. Confusing time as ideally I would like to move back to my own support network- but I'm trying not to disrupt the children. Not sure how best to proceed.
