Completely depends on how tight the girl is with her family, and then further how strict and fundamentalist the family. I generally don't give a shit what other people think about what I do, which would apply to any relationships, but at some point it just is not worth it. For that matter, I'd probably prefer a girlfriend who wasn't particularly tight with her family, or at least one who also needed their approval for how they handle their life, which it sounds like yours did whether in such explicit terms or not.
i agree 100%. my last serious gf, who i dated for 10 months, happened to be hardcore family. it didn't bother me at first, but over time, i noticed and felt that her parents really weren't warming up to me. it was odd; at first, they loved me...as time went on, though, their feelings couldn't be mistaken.
since she was 18, i was always at her house as she wasn't "allowed" at my apartment. it got to the point where i only ended up going to her house 2-3 times a week, instead of the normal daily occurence. she asked me why, and i told her that her parents and attitudes were really bothering me... she couldn't believe it, reassuring me that they love me, blah blah blah, they're just protective.
but u can't shake the feeling or perception that you're not wanted in their daughters life. shortly thereafter, we broke up.. this, among others, was the deciding factor..
