What do you think i should do?

me and this kid dom liked eachother for about 7 or 8 months, he told me he loved me and we talked all the timee and he was just the nicest guy and he always makes me feel better when im upset. he asked me out but i told him it wasnt the best time even though i realllly like him and i wanted to hangout with him more first. he was fine with that and thought it was a good idea too( he knew i liked him since we have talked about it before) so about a month ago he decided to tell me thatt he cant do this anymore and he cant talk to me anymore and he needs to move on. i was hysterical i didnt no what to do, i was in shock when he said it to me and he kept saying i thought you would understand.i kept distance for a week and then i messaged him a week later saying i no you probably dont want to talk to me but i just wanted to tell you that i understand now and im sorry for the way i reacted even though i dont like it i just want you to do what makes you happy since i care about you so much and trust you and dont want to completely loose you. he was reallly happy i said that to him and he said he did a lot of thinking the past week, he said he didnt no what he was thinking saying that to me and we decided to go back to the way we were. Things seemed back to normal after this we talked regualrly and he told me he loved me again. Now about 2 weeks ago he started acting weird and stopped answering my texts and IMs i didnt no what to think so i justt left it alone once in a while i would text him and still get no answer, this made me soo upset since im basically in love with this kid and hes ignoring me and idk whyy.. so i instant messaged him last night saying this big long thing about how im feeling and how hes really hurting me. i thought he might actually answer but he didnt at all. I got so upset about this since i guess everything he said was a lie then? i just dont no what else i can do.he talked to my friend last night and he said that i changed which i think he was lying to her because i honestly havent changed at all. i cantt just try to get over him because i have tried, i just want to no whats going on but how am i supposed to no if what hes thinking if he wont talk to me? i dont no what to do and i really love him:( please help?
