Search Results: guys get angry when they are drunk

Last year I was talking to this guy and we hooked up a couple times. It was never serious and I ended it quickly. A month of so after that he met another girl I know (acquaintance/friend) and started talking/dating her. I was still nice to him (basically just saying hi, not ignoring him when I saw him) but in no way trying to have him back or anything while they were together. Then, she found out that we had hooked up and got extremely mad and confrontational with me when she was drunk (she gets very emotional when drunk and they are always fighting and breaking up/getting back together). She told me to stop talking to him and trying to "steal" him. I just tried to calm her down and say that nothing is going on and that everything that happened was in the past. She was still angry and had him block me on everything. This happened a few months ago but I just found out that she has been telling people that when she confronted me I said "I'm going to sleep with your boyfriend whether you like it or not" (complete lie)! I'm now scared because I was planning on rushing the sorority she is in and I absolutely HATE drama like this. Should I just apologize to see if I can diffuse the situation or should I stand my ground and hope she doesn't cause problems?
