Your daughter is misguided and stupid for being with such an asshole.. tell her he aint welcome at your place nor that you approve of such a situation.. just let her know it aint cool to call someone elses husband your boyfriend? The guy also sounds annoying as fuck.. she should know by now that dating a loser like that is a big reflection on who she is as a person.. try talking to her like an adult and see what you get out of it..
