Don't let her make you into a rug. I would get out of the living together situation too since she broke up with you. I'm doing the same thing you're doing now&it IS REALLY HARD. It all comes down to trust&I think she hasn't been honest w/herself or w/you. Give her&yourself space to work things out or to at last see where things really stand-someone has to make up their mind as to what they want&stick with it. Don't despair, there are lots of us who have been through the same thing.
