I need makin someone apologize to you advise!

Alright. well it has been a horriblle week for me now that school has started & what not. But im in this fight with the guy I went out with && keep commin back to him because my feelings keep reborning. Hes just like my best friend. I know the real him, im not like all of his friends. He will go up to everyone else & talk crap about me than when it comes to me he will talk crap about them. His friendss are not as close as I am. I got to know him talked to him about his life & what he feels he comes before me. But his friends will only talk about themselfs they dont talk about his life. I found out his mom had cancer for 8 years && all his other friend sit there & tell him he doensnt know what their going through. I guess he doesnt know what its like until it leaves him.. Half his friends dont even know about his life they just care to lean on him. But the point is.. We got into this stupid fight about how he has changed & how hess pretendin to b somethin hes not. He told me he had enough of me && is sick of it && to never F-ing talk to him again. I dont knoo howww amm I suppose to make him feel like wow I hurt her.. or how am I suppose to make him come up to me to apologize & to talk to me about it. I tried apologizing he didnt talk to me && the second time I told him I dont want to go back & forth sayin crap about eachother. because its not worth it. && please dont tell me hes not worth it. because seriously If a guy broke up with u && makes you feel like crap && you say its not worth it.. what about in the end he becomes your best friend? I dont want to give up. I want to do what ever it takes. so pleasee give me some advise because it matters.
