It is great he is coming around, as Jen said, set your boundaries and start from there. If you feel you can relinquish your anger and work on your M then you are in a good state. For many LBS that I am finding, sometimes by the time the WAS wants to come back, they are too angry and hurt to accept them. Pray about this and ask for guidance.
I would meet him at the restaurant on Saturday and start from there.
