Welcome Wildflower, I m so glad you came here and posted. You are taking positive steps to get yourself healthy. This site helped me get sober, and I still read and post daily.
Is this guy still living with you? If so, trying to get him out would be a really good thing. His drinking is definitely a concern, but the bigger red flag is him checking your phone and separating you from friends. Many years ago I dated someone who started out overly controlling and that turned to physical violence. Please be careful if you ask him to leave.
