Hope you left her there

On one hand, its hardly THEIR problem. On the other hand, get a new girlfriend.

Welp I hope you left her stranded there.

dump that dirty ****. u should have left that ***** there let her use her mouth to get a ride home.who cares what happens to her

though its true people make mistakes bit that would have been valid if the dude went up to her and tried to kiss her only in my book she ran climbed on stage and kissed him she knew what she was doing she knew who she was hurting and she haste have known the outcome so she can't complain if she gets dumped

It's only Rock and Roll but I think OP didn't like it. OP, you deserve better than that.

I mean I assume it's hard for them to know what strangers are dating. So you can't really hold it against them. You can, however, hold it against your GF because in a monogamous relationship that's not cool. Obviously some implied boundaries weren't set.

Usually security prevents anyone getting on stage unless stated otherwise

just saying best pay back would of been to brake up with her and leave her ass there...

It's sad how people think he should give her another chance or that it's ok cause it was in the moment. It's not ok and op should dump her. It doesn't matter if they were famous or not, if your significant other willingly goes and kisses someone, that shows they don't care about you or the relationship, that's enough of a reason to break it off. They're old enough to know common sense and what's expected in a relationship. Op, you'll definitely find someone better, just get this girl out of your life.
