I started talking to a old friend of mind from high school. I had a fun talk with him. We talked about a lot of things. It was like the good old day when we were young. The main thing we talk about was all the mean things that he did to me. (He would lied to me, talk bad things behind my back, get mad at me for no reason, get his at the time girlfriends mad at me for no reasons, and played with my feelings to many times.) He said to me that he was very sorry for all the bad things that he did to me. And he would like to start a new friendship with me now and make everything up to me. I really want to trust him but I really don't know if I can. My question is what should I do? Should I start new and pit the past in the past.

One more thing, when I was younger I used to like him a lot. And he knew that I did. That what makes thing so confusing for me. I do not want to get hurt again by him.
