I feel so played and I'm such a fool what should I do =(?

I have been talking to this boy for a while now.I turned down so many boys for him and this is how he repays me. Me and him have been talking for a while and he likes me and I like him. I really felt like he was the one for me and that he's always constantly blushing when I'm around him and smiling and he tells me that he is never like this when he's around other girls.I have never had a boyfriend and I thought he was the right guy for me.The last time I hung out with him was 4 weeks ago and we had a good time we talked and I thought I was falling for him.Two days later I heard he had a hickey from this chick on his chest.I heard from my best friend and I confronted him on the phone and he told me he didn't kiss her or do anything with her.I was so mad at him I just hung up and started crying.I recently heard that he might be a dad and he's saying that shes sprung and he used a rubber and he's 100% sure she isn't.His friend's were telling him how can he scoop so low if he had something better which was me and that every time they talk about me he's always looking down or he doesn't say anything.His friend's are trying to hook us up but after I heard that I can't let go for what he did.We weren't going out but we were getting in to the process.His friend's were saying that if he called me right now that I would get over it like that.That just got me so mad when my best friend told me and she was telling them I know Karla she got over it the next day and she keeps to herself.They were saying well if she acts normal when he does call then she really didn't like him that much.I really do feel played and I do want to move on but my friend is telling me no to get him how he hurt me.I really don't know what to do.
