GF 23, I'm 21. Been seriously dating for ~6 months now. There's a local band that plays at bars / outside events once or twice a week that we are both fans of. So, of course we go with a few others and drink and have fun and listen to the music. Her and the lead singer know each other, and by know I mean: name, and the fact he's married and has like 2 kids... they've never hung out / talked outside of a concert that they've played at. She's been going to these concerts before me. After shows the lead singer and her will always end up finding each other and always hug for at least 5 seconds, it's awkward as fuck for me... Sometimes she'll be so drunk she'll kind of drunk hang on him for quite a while and invite him out for drinks with us, talking in his ear and shit and claiming that she's just saying that he had a good show and what not (I believe her when she says that's it). I've told her before that I hate it when she does that and should be hugging/hanging on me when she's drunk instead... am I wrong in that? am I overreacting? Her defense is that is just how she is and she cant really help it, which I honestly don't know how to respond to. She knows I don't like it when she does this. Basically I'm wondering: Am I right to be upset and expect her not to do this? Am I just overreacting? Is her excuse of "that's just how I am" really valid? Is this worth leaving her if she doesn't change? And if I am right and this is a shitty thing for her to do... what can I possibly say to her that will make her see how shitty it really is, and it's not an excuse to do it because that's just how she is when she's drunk?
