<human>: I met this girl 2 months ago and i realy started to like her but she's getting over and over back to her ex. They were in relationship for 5 years, and it's her 1st relationship. He is douche and they break up every time and then she call's me, we make out and day after she get back to him again. I realy like her and i know she like's me but i don't know what to do. So any advice would be great. We have few mutual friends and one of them tomorrow is celebrating birthday and we both gonna be there so i don't know what to do. P.S. Sorry for my bad english, it's not my native.
