Is he a toxic guy?

A guy I'm seeing says he fights a lot with his friends and has had fallen out with several friends, and casusl girlfriends who have unfriended or unfollowed him on social media. Some of his university friends are still friends with each other and they still follow him but he no longer meets them even though they all meet each other. He himself once accidently slipped out that he fights a lot with his friends but quickly said that in a fun way. He has a drinking problem, goes out to drink everyday, sleeps around and is a chain smokerIs he aggressive? Or has anger issues?
