Confused

Today my ex asked me to call him...I did and he told me that he thinks that the way i broke up with him calls for a redo and that i should start to date him agean. Well i broke up with him because 1 he cheated on me 2 because a girl who i thought was my friend would not stop talking shit on us and keep telling me he was cheating on me agean and 3 because i got told he was going to break up with me and ya i know that that one i shouldn't of listened to but i don't like to be dumped and was scarred he was gonna dump me so i thought i would dump him first. Well now he says that he didn't cheat on me after he came clean about it and that he was not planing to dump me but he lives in a different state and so i never really know. I don't know if i want to get back togeather with him but he is right when he says was not a fair break up, but i am now starting to wonder if maybe i was not liking the fact that it was a long distance relationship or what but i don't really know guys are really confusing and i am confused on what i should do :( sometimes i wish i was never really almost 18 sometimes i wish i was like 7 or 8 because i cant help but think maybe it wouldn't be as confusing or complicated.
