I need help. i want him back. i still love him?

k so i broke up with him cause we were fighting before and i was mad then someone said he was going after some other girl so i asked him and he said no, but he does like her. i got jelous and called it off. i tried getting him back that failed. so i tried getting my other ex - his bestfriend- back that failed so i tried for him again then went to his other best friend. and i just kept going between the 3. i know ive screwed up majorly. its been 53 days since me and him have broken up. he is now graduated. and i rarely see him. i still love him. i still would do anything for him. ive tried to b with other guys but no guy compares to him. not even close. he says hes evil but to me hes my everything. i know he probs hates me for going after his friends. i want him back tho. i dont know how. everytime i ask for him back he says no. i always say i was just mad and wasnt thinking and i made a mistake, that didnt work. i wanna send him a text or something. but it needs to be short and something that will catch his attention. i dont know what to put. cause if i was to it would be really long and he wouldnt even wanna listen/read it.
