if you really think she is the one you want to spend the rest of your life with then I would be inclined to accept that she doesn't want the comitment of a bf at this moment in time, let her know that you are ok with that and let her know you are there for her as a friend if she needs you. a 'thinking about yo, hope you are ok' txt once a month or so should be ok to keep contact until she is ready to rationally decide. let nature take its course, it could be as simple as her bp has changed and she cant handle bfs in this state. if on the other hand you do not see a future for you as a couple then stay well away and be gentle with yourself, don't go opting for he first girl that comes along as relationships formed on a rebound usually do not last.
