HELP!! What do i do about josh and caleb!?

So I was going out with this guy, Caleb...He was PERFECT! We had been going out for 4 months. My longest relationship, first kiss, first love. He broke up with me in july and its now september... I can get over him. I went out with another guy, Josh bc i liked him and he liked me but i felt like i was constantly comparing him to Caleb. So i broke up with Josh. Josh wont talk to me now. :/ I told my friend jenny that i was single in our flucotime(like a homeroom) And Caleb heard me, Jenny said his face lit up. I saw it too though, some of his friends have told me he likes me but i just dont know what to do. I should probably mention that Caleb called me a , b****, a fat b****, and tons of other things(In august after we broke up). im not fat, not a *****, not a ! I weight 119 lbs, 14, and i have abs. If Caleb ever asks me out ill probably say no bc of those comments. I just really need help. ://
