Do I give up trying to be with this guy?

When I was like 15, I was in this relationship with this guy. I guess you can call it puppy love because we use to stay up all night talking on the phone and he was my first. We dated for a year and some months. after we broke up we still remain friends but, the only time we talk to each is to give each other relationship advice. he was like my best friend, I could tell him anything. I'm single and he was dated this girl they was in a relationship for 4 years and they broke in the summer of 2009. I was there for him every time he needed someone to talk to or just for someone to listen. he could call me at anytime to tell me about his problems. well somehow we start back messing around and I guess we got feeling for each other but he would always tell me that he wasn't ready for a relationship . I guess my feeling got stronger for him and his didn't and like now all we do is argue about any little thing and yesterday he told me that he was really feeling me but he can't see himself with me because I hurt him just like his ex girlfriend. I was trying explain to him that he shouldn't hold that against me because I was younger and really didn't know what love is but now since I'm older I could some him that I'm ready. so the questions I'm asking is should I let him go or try to win him over.
