dude, the ex was cheating,(that doesn't make any sense bu whatever) plus you don't just stand their and let someone talk to someone you care about like that!? he deresved it. but yeah, kissing was a little balsy, if she would have kissed you first then its different, oh yeah if you guys were drinking then talk to her when shes sober. Women tend to say things they don't realy men when they drink.
