HELP !!! Family Ties

So my boyfriend feels like my family is phony ( in which they are). But it seems like he wants me to cut off all ties. I must admit my family are sh*t talkers, yes they have talk about me and I had address the problems and my family chooses to tell me what ever to end it. I am perfectly fine with expressing myself to my family because at least they know how I feel. I know how they can be and it does not bother me because all I’m doing is keeping my distance but it’s like he want me to antagonize them for what they say and cut off all ties and I don’t feel like the stuff they say is so Dramatic for those desperate measures. Why I can just be cordial with everybody must I cut them off 🤔. Mind you he has the same problems too with his family, But he can be cordial etc. after explaining himself but he must say I’m phony and fake because I do the same thing 🤔. So what is it.
