Tiffany, Just take it easy for a while and let go. She may realize that she was better off with you, and make a compromise, but if not, please don't be too tough on her or yourself, as we are all imperfect beings, and life is full of bumps in the road. I would not be looking to rebound in another person or relationship at all, except to vent. One day at a time, and easy does it.
