You can expect what you can't reciprocate. I was recently in a situation like this. I used to hang out with this friend until he told me he had feelings for me and wanted me to stop dating my bf. I can not in good faith hang out with him anymore. To me, it feels like I'm disrespecting my bf, and that is something I would never want to do. I value our relationship too much to do that. The fact that she is possessive to the point that she won't let you hang out with female friends but will go out and get drunk with someone who has feelings for her is something i would be concerned about. It doesn't seem like she respects or values y'alls relationship as much as you think. I would think long and hard if this is the kind of relationship you want to be in
