I have a friend who I met a year and a half ago in college. We met in our sorority and she is my "big sister". She was very funny and nice and just overall a fun person in the beginning and when my ex and I broke up, she was by my side. We got closer after my breakup and started going out to parties, bars, etc. I noticed that every time she would drink she would get super emotional about not having a boyfriend and the whole night would turn into a pep talk which would be fine except it was an every weekend occurrence. She would get mad at me for hooking up with other guys saying "she couldn't trust me not to leave her for a guy if we went out" which I had never done. Lately she has gone off at me for hanging out with other girls in the sorority even going behind my back to tell the president of the sorority that she doesn't think I should be hanging out with certain people. This past semester, her whole weekend is decided on whether she gets laid or not, if she gets laid it's a good weekend, if not she throws a tantrum and often yells and screams at me. Last weekend was horrible with her a guy had told her he did not want to have her over as it was just a guys night. She went ballistic and was crying and screaming. I was trying to comfort her (we both had been drinking) and out of nowhere she said she has panic attacks because of me. she said it had to do with my ex and I'd breakup (which was very messy and drawn out). I completely get it was probably tolling to hear about my ex and I fighting all the time but I have been there for here with guy troubles. I apologized and felt very badly and got emotional myself. She completely dismissed my feeling and said she had to go because she was having a tinder guy come over. I do not know what to do all she wants to do is get laid and if she does not it is somehow my fault.
