Hi CC - I think your bf's parents must accept you, otherwise they'd be badgering their son to try and find a place, and wouldn't want you staying there so often, By hiding away, you're probably making THEM feel uncomfortable. They must feel that you don't like them, otherwise you'd be making more of an effort to integrate into the family. Do you offer to help with meals, wash up and so on? Buckling in happily'll show them that you want to be part of their family group, or perhaps you just need to speak to these people on your own, and explain that you feel a bit like a fish out of water. Good luck.
