Man... Both of you are good at making difficult-to-read posts.
How old are you? Are you old enough and ready for a serious relationship? From observation and experience, at a younger age it's hugely difficult to have a serious relationship where you lean on the person and they lean on you. To me, it sounds like she isn't ready for a real, serious, intimate relationship right now. Honestly, in a serious relationship, both need to be eachother's numero uno. Your spouse/significant other should be your best friend, otherwise there can be quite a few problems (just look at all the marriages that don't work out because the two can't really stand eachother).
My advice: Talk to her about this like, but approach it in love and humility. The problem isn't always on their end, it could be something you're doing differently. Be open about it, but recognize that if you two can't communicate, unless you both learn how to, a real relationship just isn't possible. It may be that she just wants to be friends for now, and that's fine. Try not to force anything that she's not ready for

.
That's just my two cents...
