This is all really tough. As soon as I read the first page (wife really cold and distant, constant texting, always gone) I could feel alot of the same thing going on in my own sitch. (She's said there isn't another man but I wouldn't be surprised if there was). It's all so hard to look back then wonder who this new person is who replaced my wife. It just makes me shake my head sometimes.
Mine has plans for me to move out but I haven't told her yet that I'm not going anywhere. Things are going to get a lot worse before they get better.
Take care of yourself. Exercise, see friends, GAL, treat yourself. I'm pullin' for you.
