Op again.

Sorry, I forgot to mention I live in Canada - BC specifically, and 19 is the legal age for drinking. I understand why her parents don't approve of it though, since her mom's brothers are big alcoholics, which I won't go into right now.

Thanks for the advice, I think I'll go with the year lease basement suite. It seems the best choice money-wise and privacy-wise. Will it be weird to... not visit them upstairs a lot? I don't mean I'll avoid them, but I just don't think I'll want to go up and visit them often. I mean, I expect my gf will want to go hangout with them often, but I just want to have a life apart from them downstairs if I do end up in that situation. Is that.. weird... antisocial-like..?
