Should i tell my gf that her parents are getting on my nerves?

her dad looks at me like i'm a roach that needs to be stepped on and her mom thinks i'm the maggot in her cream. all because i didn't throw out the condom in the trash and left it in the bathroom. her parents found it and since that time it's been hell going to visit her. so i'm bagging their 18 year old big deal........she doesn't get it that i'm not feeling it going to her house anymore.......
