Am I right or wrong in this situation

Me and this girl were talking and she tells me about how some guy just told her that he loved her then I was like wow that's crazy then a few nights later I asked what she is thinking about and she says guys I just say right on then out of nowhere shes like "wth is wrong with you i told you some guy said he loved me and im thinking about guys you act like you don't even care." What am I supposed to do talk about how I wanna kick the guys *kitten* or tell her im the only thing she can think about idk just seems like she is trying to make me jealous
