danziggy...

sounds to me that you are dealing with someone who is confused about her own needs and desires. I hate to say this, but it sounds to me that she may be staying with you out of "comfort" and fear of what could happen next...

You deserve to be loved 100%... and to be someone's everything... don't give yourself away to someone who isn't willing to give you as much as you give to them (and no, I am not talking materially here).

Good Luck.. and many hugs..
