For now, do what Dad suggested. Just step away and deal with your own feelings.
In the mean time, keep posting. What are your plans? You mention that she was graduating and that the two of you met in college, so when did you graduate? Or have you? Are you working on your own life? What's the big picture?
A relationship can be a beautiful part of that picture, but it isn't the end all be all... what else do you have going on?
P.S. For the record, yep. I have been there. Minus the restraining order, but I understand.
