I went to the movies with my best friend(a girl), but her boyfriend is pissy about it. What's up with that?

She's having her cake and eating it too. She's got the boyfriend for all the boyfriend stuff, and you for all the comfortable stuff. She's having trouble maintaining him b/c he's a jealous type so it isn't the easiest cake, but she's loving having 2 people want her. She most likely knows you like her, cause girls always do.
