Sounds like to me your feelings are still to much like an open cut, for you to be able to talk to him right now, without spilling your hart out to him.
I don't think it would be wise for you to call him right now. He may say some hurtfull things and the progress you have made will be crushed.
Hang in there. You are doing great. You have made it 5 weeks. Keep it up a little longer.
We all have our set back days, and I am having one today too.... But I know if I call him it would do more harm than good.
I wish I could tell you a quick fix to help, I would share it with all the LS, but unfortunatly, the only advice I can give, is to let yourself deal with the emotions.
Tomorrow will be a better day.
