Does this make me a terrible human?

My boyfriend and I have been dating eleven months. Over last summer, he had a bunch of dude friends but I was having psychiatric problems so sometimes, it just happened that, I called while he was with his friends. OR texted. But I was always distraught and needy. I'm better now but his friends don't want to hang out with him it seems. I don't know how it could be completely my fault. If he left the room to console me, they'd have hardly noticed in such a big group. It's possible they grew apart maybe? But anyway he always gets angry with me and brings up how it's my fault he's lost all of his friends. At this point I'm headstrong enough to hold my own- and I encourage him to hang out with people and do whatever he wants but his friends don't even speak to him anymore. He gets SO angry at me and says I ruined aspects of his life. I am NOT making him stay with me. I want him to get his friends back more than anything. Because now he's ruining my friendships to get back at me. What do i do!?
