He said he appreciated how great I've been with his kids the last 5 years, and that I'm a very good person, but we aren't right for each other because I drive him crazy. I was crying and told him he would regret this and he said "that's what you always say." Then he told me I needed help for my anger and he's emotionally spent. And also said that I was too weak right now because I'm losing my hair. How callous and cruel is that!! He said he doesn't have a problem with alcohol (although he's been to rehab 3 times). But anytime I've tried to end it with him he's threatened to kill himself and calls me 100 times a day.
