I was put in a similar situation, I thought long and hard about the matter. I finally decided to at least give it a try once to see how he acted, how I reacted, to see what he wanted, etc. Atleast I would not wonder the rest of my life. It is atleast worth a try, if you you do decide to go I would go somewhere public, just in case. Not everyone deserves a second chance, he may earn it though.
