please help..

I'm 16, almost 17. On April 29, 2016 I started talking to s guy (let's call him B) and we talked for a week and got together on his birthday, May 6, 2016. Before this, u had always thought he was cute and his friends were quick to tell him after I accidentally let it slip at a school activity we all had together. As we were together, I was a virgin until May 25, 2016. The feelings I had before that day were strong. So so strong for him & I could tell that the feelings were mutual between us. He accidentally said he loves me and totally freaked thinking he said it too soon. School ended June 6, 2016. We stayed off-on throughout the summer due to issues we had troubles sorting out. We always got through them though and came out stronger than ever. This is where things get bad.. He wouldn't let me on his phone and everytime we did argue, he would text his ex-girls friends or "hookup" buddies to make me mad. I'm not innocent here either, I would "talk crap" about him on Twitter.. Mostly cause he had my notifications on and I knew he would see it and we would fix things out. One night, he ignored me & turned off his read so I wouldn't know if he read his messages and talked to his "hookup" buddies, so I broke up with him. A few days later we worked it out and all was swell for a while. We hadn't seen each other in a month due to family issues and vacations so the tension between us was rising each day to the point I wouldn't bother to text him cause all we would do is argue.. So I broke up with him again. This time, he took me back and we finally hung out and worked things out better. A few days before our school year started (August 18) we broke up. Well, that following Monday he messaged me wanting to work it out so I said sure.. I loved him, I couldn't let him go. I ended it about 3 weeks ago. I found out he cheated on me.. Twice. His friends knew about the 2nd girl and didn't tell me. We argued everyday even after we broke up. We kept in contact.. Until he recently got a girlfriend. His friends told me that he said it was just for sex and to make me jealous.. I have a boyfriend now. I like my boyfriend dearly and I've made many friends since B & I broke up. But, I still want him in my life and we keep making eye contact and bumping into each other during school and I feel like if we both was single, we would come back to each other.. Should I have tried harder? I still love him. I think I always will but, should I just move on? I know I have a boyfriend but I still look for B in him. He doesn't do the things B done and it doesn't give me the butterflies like B had given me. Did I move on too fast? Help..
