How do I get over my friend with benefits?

There's this guy who has been talking to me on/off the past 2 years but I always had a boyfriend. I'm finally single and about a month and a half ago he asked me to go out on a date but I told him I wanted to be friends with benefits. We slept together a few times and after the first time we slept together I asked a mutual friend who knows him better than I do if there's anything I should know about him and she said not to get involved with him because he likes to be in control so I completely changed how I acted towards him and became very cold and distant and bitchy only because I didn't want to get hurt. He knew I was still going on dates and he didn't like it and told me he didn't like sharing me etc etc. When we hung out he was very affectionate almost boyfriend-like but then via text he'd be cold and said he's not a good texter. We got in a big fight a few weeks ago that he started because he was being moody and when I started shutting him out in the argument he kept apologizing and trying to change the conversation. This past week we made plans to see each other again when I came back from my vacation and in that same conversation he asked me if I was seeing anyone and I told him I was talking to people but not necessarily seeing anyone and that I felt shitty about myself because of the things he said to me in the argument and he ended up ending the whole arrangement with me saying that there are things about me he didn't like blah blah blah and we didn't end on good terms. It's the rejection part that sucks and the fact that I know he would've liked my real personality but I tried so hard to be someone I'm not that I screwed it all up. I'm not sure how to get over it and my feelings are a bit hurt. His best friend who I was very close with when we were kids is also interested in me now and doesn't know about the arrangement but I can't stop thinking about the friends with benefits. I wish I could get a second chance to start over being my real self. How do I get over him/the rejection?
