So they say don't contact your ex well its been 4 months now and haven't heard anything from her. She dumped me. I don't see what a casual hey how are you text would hurt at this point. I see her driving around occasionally and she definitely pauses when she sees me. She kind of ended things out of the blue with no explanation at all, so I wonder if she would reach out even if she wanted to. I think at this point I need to either just forget it or make a move...
I don't think she would swallow her pride and reach out first, honestly.
