He is dismissive of your friends
Any time you bring a new friend around your guy, he should be asking her questions about herself. He should be engaging her. Some have the mindset of “not my friend, not my responsibility” and think they can just give a dismissive wave from the couch and their job is done. Your man might be smart, funny and kind. But your friends will think he is not interested in your life if he doesn’t speak to them, because they are a part of your life. Tell him that he comes off as rude and brain dead by not speaking up cordially to your bffs.
