will anyone help me get him back please :( ?

I love him more than anything else in this world. He used to tell me that after God his mom and I were all he had. but suddenly everything went wrong. he broke up with me by just telling me that he doesn't want to be with a girl anymore. the night before my father had bought me a vaio laptop. my previous one was broken. I got really excited and wanted to let him know this. and told him. he broke up with me the day after. It sounds irrelevant but this is exactly why he broke up with me I guess!
2 monthes later I chatted with him on facebook not as me but as someone else ( As another girl and he didn't know it was me and never found out either). I wanted to make him miss me so that unreal girl on facebook sounded really bad. a selfish girl who only wants a boyfriend for money ( that's all)
he rejected her after he found out this and said:" you girls are all the same! all you care about is money. you are all jerks and I hate all of you. now go away "
I cried really hard. so that was the reason he broke up with me! he was wrong!
all of our meetings were in the street just walking together I never asked him to buy anything for me.and he sent me text messeges just as many as I sent him. how can he think about me like a selfish stupid girl? I got heart broken more than ever.
as the un real girl on face book I told him as a reply to what he said:" So what? you have to buy me everything I like ! take me to most expensive restaurants and...." by telling him this I wanted to let him know that he was wrong about me. but he said again what he had said before to that girl.
sorry I got this too long and I am sorry for my awful grammer as well cause English is not my mother tounge . there is something you should know about him: he lost his dad when he was 10 and since then he has worked really hard. he left university because he didn't have enough money. that's why he may sound sensitive. but I didn't do anything wrong I swear. I think that telling him that my dad has replaced my Vaio may have made him assume that I am showing off. both my dad and his money!
but All I really wanted to do was sharing my happiness with him. he knew how bad the previous one was!
he is 24 and I am 20.
It's been 3 monthes I haven't seen him or talked to him or even texted him. I am dying. I cry every night. he hates me for a wrong reason. we are still friends on face book though. I don't know why he doesn't unfriend me he just hates me.
the only way I can contact him now is by phone and facebook (the wrongest way) I can't see him because we met on the street.
please help me get him back. what can I do? I am so miserable.
