Is it over?? Should i talk to him?

ok well here it goes. me and my [EX] boyfriend,moe, where really serious about eachother. [he is my cousin by the way] i started liking him the very first time i layed eyes on him but i only saw him because i visited my aunts house before moving to another place. and after 1 year we moved to were he lives. him and my brother would go to the pool everyday and like every girl would do, i followed my brother because i liked my moe. he would flirt with me and stuff but i never actually thought he liked me. it stayed that way for 4 months before i finally figured out he liked me. i moved to another city. befor i left i made him an instant messenger so we could talk. when i got to my new house i told him i missed him and one thing led to another and we were together. i loved him so muchhh. we started talking about our future and he said he wanted to ask for my hand in a couple years,but we would get in fights because he wouldnt be online enough. [there was no other way we could keep in touch]i broke up with him 2 months later. after a couple of months i regreted it. i was depresed for so long. and when my sisters wedding came him and his family came. i decided to talk to him so i did and he told me to call him. i called him the next day and we talked about marriage and kids and our house etc. after a month my sister started saying that he didnt like me and he just wanted me because he didnt have noone else. so i left him again. and after i went over his house i loved him all over again. and when i left i cried for a week and decided to message him on myspace and all he wants to do is be friends because he thinks im playing with him. and it makes me sad knowing that HE doesnt want to be with ME. im so confused and i dont know what to do. i say hey and he doesnt even message me back. what should i say? what should i do? please help.
