Welcome to the board. I hope you can find the support you're looking for here.
I'm not quite certain you're looking for bp support though, having read through your post. Not that it's truly going to matter all that much, but I'm not sure why we're the board you chose. What about this relationship says "bp" to you? Are you bp? Are you struggling with it?
Since you asked...as to your description of your girlfriend's behavior, I'm going to be frank. No, she doesn't sound nearly as committed to the relationship as you are. She's flirting around with other people, dropping subtle hints about how she'd rather be making out with them, dodging questions about the longevity of your relationship, and she won't talk about it. You want definitions. She wants to be left alone. Doesn't sound like a good match to me, but then -- I'm not you. But I think it's time for you to muster some self respect and cut her loose.
I hope this helps and doesn't offend,

It is a melancholy of mine own, compounded of many simples, extracted from many objects, and indeed the sundry contemplation of my travels, in which my often rumination wraps me in a most humorous sadness. -- William Shakespeare
