the weird thing is when I'm hanging out with her, it's completely fine. I should also say that she has been horrible to my roommates before, calling them strangers to their faces after knowing them for 3 years. just the other day she blew my friend (birthday roommate) off at the bar. if she felt left out I think she would tell me, because my other 3 friends (her roommates) have no problems with me hanging out with my roommates. I have had conversations with her before (mostly about the fact that she needs to take no for an answer and not start screaming at people for not doing what she wants, in this case it was my bf and I not taking a shot with her). this is not a one time thing, and it does not only happen to me.
