So I'm a girl and I've had a crush on a girl for a little while now and we've talked about bisexual feelings a bunch and I know that she's bi but I've never told her how I feel and there is this guy that's liked her for a long time and she's been talking about how annoying he is for the past few days but today she suddenly accepted his feelings and I feel really crushed and I just don't know what to do because I'm going over to her house this weekend and I was planning to flirt a whole bunch and I'm hurt and confused and what do I do??????
