I dont know where to go...

my boyfriend of 2 years just broke up with me. i didnt think we were having a bad time seeing as we were always talking about marriage and what are plans were when he got home. he is in iraq. he often tells me that he thinks i cheat on him even though i never have and never will. he is jealous and a little controlling. I had my brakes fixed by my moms friend and told him my dad did them when he fouund out i lied he said i was not what he wanted i wasnt his girlfriend anymore and he could never be with someone like me. im lost, we have been together for almost 3 years, we only had 2 months to go untill his R&R. i dont know whats going on. im so hurt i dont know what to do.
