What should I do about this issue with my boyfriend?

Well you see… I’m 15 and my boyfriend and I have been going out for almost 5 months all up. We broke up around 3 months of going out because 1) I still had feelings for my ex and 2) He was pressuring me into doing sexual stuff with him, that I wasn’t ready for at the time. And to this day he still doesn’t know the first reason we broke up… Anyway my ex and my current boyfriend are like best friends… and when my ex broke up with me for the reason that he couldn’t see me enough because he was ‘so busy’ and felt it wasn’t fair on me, and it would be easier to break up now, I… I’ve never been so hurt in my life. :( About a week later my current boyfriend asked me out, although he was one of my best friends before hand. I thought he was so amazing and worth it, but as it turns out, everytime I see him he always trys to do stuff with me, and he’s never satasfied with just making out or whatever. And I’m not attracted to him. :( And I am so, unbelieveably attracted to me ex. I still cry about him breaking up with me to this day although it was like 5-6 months ago. What do I do? Please help. :(
