5 months ago I found out my husband of 17 years had been cheating for years. We were honestly happy and he said if I hadn't found out he would never have left the marriage. I kicked him out, tried to work on it, went to therapy, but he won't talk, won't explain and has been so dismissive. I know I can move on, but I get overwhelmed and text him. I know I shouldn't. I've blocked his number, had friends who let me text them instead. How do I stop this???
