My girlfriends flatmate has skitso tendencies. He became angry and annoyed far too many times with me, when finally he did it one more time, so I just walked off to avoid his arguments only to be followed and told what a cunt I am. My girlfriend doesn't seem to understand why I now have a problem with him and wants me make up with him.
For some reason she seems to think he is a friend when I know he just generally is a horrid person. He's also admitted to being a smack user, a needle sharer and had a cock in his ass.
Am I being that unreasonable?
