boyfriend and dating issues help!!

im 15 by the way… ok so I’ve been dating this kid. and I think hes the one. we were both virgins when it started and now were not. do the math. and I promised myself id lose it to the person I love. and thats what I didsince the first time, weve had sex 2 other times (3 total) but thats like beside the point. lately…hes been acting like a huge as.shole. im aware im not the smartest person out there. I have my very blonde moments (take no offense of this) but hell like blatantly call me stupid at the wrong points during a fight. and like not only that but hell call me a ‘stupid b.itch’ which pushes it. he tells me to shut up all the time. and then when were fighting hell drop the usual ‘then break up with me’ line. which really pisses me off. because I REALLY WANT TO be with him. I fu.cking love this dude. hes like part of me now, but everytime I talk to him he hurts me emotionally. so like bits and peices of me die, and if we were to break up (almsot has happened once of twince) then the part of me thats like him, would die. and thats a big freaking chunk. (you follow…?) but so like a week-a week and a half ago, we got in a fight (of course)and you know those lines that someone will say before the stirck you? yeah well he pulled one of those. I told him he was on thin ice because he was being an as.shole to me and not respecting a friend of mine and he continued to do something (sexual) when I asked him to stop. (the sexual thing wasnt like intense though…just a han.d job) but anywho, he said ‘don’t you ever terll me im on thin ice ever again’ and I know it was one of those lines because of my dad. but this isnt about that. but hes never actually hit me though. just like emotionally if that makes sense(?) and im like always the first one to contact eachother. he like doesnt call me anymore, or im me or message me on facebook or whatever (he lives 2 hrs away and he doesnt have a car and I cant drive so we dont see eachother that often) I always am the one to cal ect ect ect. but you can blatently tell he loves me, like if you knew him, youd be able to tell. a lot of myfriends tell me to break up with him, they tell me that hes using me, that im his booty call. but I dont belive it. but its also wicked suspicious because on fb (facebook) we had a break in the beginning of the yr because he kissed someone. and I found out through that person and confronted him about it. but after the break I sent him a relationship requestand he NEVER answered it. I finally gave up after liek 2.5-3 months. he kept saying because of the snow storm he didnt have internet, or the page wouldnt load. and I beleived him at first but then I noticed that he was commenting on things and all that. s again, confronted him and hen was like “is it needed?” and like ‘I didnt feel like it/feel it was needed’ all that shiz. so it like led me to beleive that e was fooling with girls, and didnt accept the request because he didnt want people to no he was dating or something along those lines. but if you knew him, hes not the type than get get girls…easily…at all. so tonight we were talking and ended up on the ohone and I was just informing him of like some things in the realtionship that havent been going too well lately. and I don’t know just went south from there. and he was like ‘we cant do this anymore, its tearing us apart, its hurting us both too much.’ which is mostly true but I love him I cant let him go. and I was blatently bawling my eyes out, and it sounded like he was trying to keep it in too. but he said he was crying. and im bawling ridiculously. and like if we break up, he tends to leave things that upset him, so that means we wouldnt talk or anything. but I made him promise that when we break up, that hed try to still talk to me, and not ignore me in every way. and he promsed. and he keeps 99% of his promises. but somehow I got it so that we would give it one more chance, and continue it for a bit longer and see where it goes. but I like need him in my life, this seems pretty legit to me. hes the best thing that has ever happened to me. and I dont want to lose him. I lost him once and I failed my classes, and was like really depressed (more so than usual) and slightly suicidal (but would never like actually go through with it). WHAT DO I DO?!?!?! HELP?!?!?!? OPPINIONS??!!?!?!? ADVICE?!?!?!?!? I WILL ACCEPT ANYTHING!!! just please please please help me
