TITLE: I'm (23/m) fed up with her (19/f) parents
POST: I've been in a relationship with my girlfriend for 1 year and her parents never liked me. 'You use her, treat her badly, you act like an old guy, you guy's won't make it .. yadda yadda yadda'. This has been going on for a year. I have told my girlfriend and her parents that I dislike the way they treat me. But it doesn't change a thing. I don't feel like keeping calm anymore. I don't want to come over at her house anymore. I am done. 

Is that reasonable of me? Or will it push my girlfriend away? (she agrees with me that her parents behavior is very wrong) Or do I need to suck it up?
TL;DR: 
Her parents treat me like crap and I am fed up with it. I don't want to see them again. I want an apologie.
