I LIKE HIM BUT IM SCARED. !! help?

Hi Guys! I realy need some help here. So I just recently (a month ago) got out of a BAD relationship. I was treated badly, screamed at constantly, always was put on a "guilt" trip and he would act very controlling. This relationship lasted for 2years and Im glad to be out of it now. Im having a good time having fun with friends and all. However, I've gone on a couple of dates with this realy cute guy I had a crush on. he seems to be very fun, adventorous, confident, nice and is such a gentlemen. Just yesterday he asked me what would I say if he told me to kiss him. I said "No", and I found myself acting very weird after this. I know he noticed because It was just very akward afterwards. He was still being Nice though. We've gone on three dates already and I can say Im scared in a way because I feel like I already like this Guy ALOT and I just don't want to mess things up, or move on too fast. Im scared of being mistreated or getting into a bad relationship ever again. I don't want him to think Im immature or anything(if he doesn't already). I realy DID wanted to kiss him but I don't want him to think Im easy or anything like that. HELP! I don't know what to do? I Like him ALOT and I don't want to push him away. What can I do for him to know that I like him but aren't ready for a relationship?
