Me and my girlfriend have been together for about a year now. I currently live in a house with 3 other guys who are my age. One of them is pretty cool, very polite and doesn't ever poke fun of anyone. The other two roommates are really annoying, if we're ever all together they make jokes about me and my GF. They make fun of her and her breasts and me for me in a serious relationship and things like that. I've told them to stop numerous time but they still keep doing it, I feel like they get a kick out of seeing me get all flustered about it. Worst part about it is they're really nice to her when she's around and she thinks that they're her friends. I've had instances where I would be angry at them from the day before and I would come off really bad and my girlfriend will poke fun of me in front of them for being angry. They'll poke fun of me for it and shell join in. In my mind I'm just like if only you knew what they say behind your back. I want to tell her but at the same time I don't bc I don't want her to feel bad or uncomfortable around them bc I do live with them and I don't want her to stop coming over. I just don't know what to do. Any advise?
