I am 26 years old woman who has been living with my boyfriend for two years. Sometimes he can be the most loving, generous, considerate person in the world, and then suddenly out of nowhere he will turn into a completely different person. He will stay out all night, drink until he passes out and say the most hurtful things to me. He left about a week ago after starting an argument with me, going into a rage and telling me he couldn't even look at me. This Jekyll and Hyde behavior has been going on for the past 9 months. He refuses to go to the doctor or admit anything is wrong.
Has anyone else experienced this with, and what did you do to convince your SO to get help? I try to be understanding, but I don't know how much longer I can put up with this.
