I feel really bad for you in your sitch! Please try and keep positive. Try not to over analyse things (I tend to do that), and stop the crazy thinking (I don't think you're crazy, but I know how I was feeling when my H was having his EA. My thoughts would just spiral out of control, and I would get very obsessive about everything. It feels like crazy, but it isn't - quite normal for you to feel this way, but you must try and get it under control - it was what helped me, anyway). Just let things go for now, and keep calm. I know we all need someone to talk to, so try and get into see a counsellor, or your church's pastor, or someone like that. And vent here, if need be. We all understand.
There are no guarantees in life, and there is certainly none where our H's are concerned. Your H may never step up to the plate and be responsible, so you have to try and be the strong one, for now. Be your own best friend!
