When my boyfriend gets really drunk he gets very angry with himself. He talks to himself out loud and says things like. “If you ever treat her like that again I’m going to wrap my hands around you neck and kill you.” “No one cares about you, your a fat fucking piece of shit.” “Shhh… Shut up, your an idiot.” and so on…. Not of these things have any meaning in our lives. He is a great Dad and boyfriend. I am not scared of him when this happens. It is annoying and worries me. Could this be a multiple personality? should he seek help?
