So sorry to hear this. I've been following your thread and just signed up a few days ago. Hang in there man. You are in a tough spot, must feel awful. This is a difficult time.
Your fear is rational and totally valid in this situation -- but it is not serving you. Take care of yourself and realize that EVEN THOUGH IT HURTS, you are doing the right thing. Well at the very least, you are doing the "least wrong" thing. You are absolutely right with deciding to cut things off and go dark if they aren't going anywhere. Now stand by that decision and prove to yourself and to her that it was the correct one.
