Do you think i made the right choice?

okay i recentley ended my relationship and i wanted to know if you agree this was the right choice? right here is some background information, i am 15 and he was 17, we have been together a year and a month, he was definatley my first love, he meant the word to me, and ive had past boyfriends but none of them meant anything compared to him. okay our relationship started as a close friendship and then i told him i liked him and then the next day he got with another girl, and so i was like how could you do that? and he was like i didnt mean it to be like this, i was already getting with her before we even met, so i accepted i needed to back off, after all he was in a relationship and i know my boundaries, so i left them to it, but he still spoke to me alot, so i spoke back but that was it, and then one night he asked me if i still liked him, and i said i will be honest yes i do, and he said i think i like you too :/ but i dont know what to do, my relationship isnt working, and so i said well end it, dont lead her on, so he said he would sleep on it, and then the next day he text me saying that she finished him, so i asked why and he said because he apparently cheated on her, which was a load of rubbish, but i didnt think anything into that, but we didnt get together straight after we carried on getting closer for a couple of weeks and then he asked me out, and i said yes, and we had a really nice relationship, i trusted him with my whole life, and we both had seperate lives so we went to stuff away from each other, but then like 8 months into our relationship he went to a sepearate party to me on new years eve because he did buy me a ticket at first, but i was having a family party so i told him to give it to a friend and still go, because i trusted him so i didnt worry, but then like two weeks after i found out he got off with another girl that night and i found out from an anonymous person on formspring (an annonymous question site) so i didnt believe it so i asked him and he denied it by replying saying "hahaha that actually made me laugh, no that isnt true xxxx" but they carried on with it, so i asked the friend he went with that night, and he said he didnt know because he was too drunk to reember what my boyfriend did, so i started doubting him, and then on formspring someone gave me the name of the girl, and so i asked her about it and she said yes we did kiss but thats all, but thats still cheating right? so i was so upset and i told him and was so angry he lied and still saw me and didnt even act any different (obviously not feeling bad) so we had a chat and he said that he was drunk and it dint mean anything, but then i find out he met up with her twice after that, they didnt do anything they just met up with some other friends as a group thing but i didnt no anything about this he obviously said he was doing something else to me, but then his mum asked why they were all in the house when i was at his one night, so he was like oh just for abit cause we were bored, so i was like what? so he told me he just had some mates over so i was like okay, so when i found out it was the same girl as he kissed i was so annoyed and he had been texting her so i ended the relationship, but he constatly spoke to me and was like please give me one chance ill stop all contact with her and delete her number and you can keep an eye on my phone forever and ill delete facebook i just need you, im sorry i misused your trust and i shouldnt have, so we met up and i took him back because i missed him and still loved him, but somehow this made us connect more and we were even more in love, and we just were back to being even closer then before wierdly, but i turned from a layed back girlfriend into a complete control freak, which he noticed but was fine with because he knew he made me like that, so he never complained, and i just completely freaked out whenever he was out, wandered who he was with, and where he was and i just didnt feel any trust in him, but he didnt do anything wrong (apart from little silly arguments over stuff) for like 6 months. but then recently he went on holiday, with a friend and his friends family, he was really cute when he text me on holiday like saying how much he missed me and loved me, so i was like hes so sweet, but then he gets back i find out from someone that he has made a facebook without telling me with the name spelt wrong so i couldnt find him and wouldnt find out, so i asked him about it and he says its a fake someone made of him, his exact words were 'its a fake, dont you think i can spell my own name? i love you xxxx' and then i was like okay so i believed him and i put in my fb status 'dont addd .... .... its a fake account' but then his mate he went on holiday with commented like 'he told me this was his facebook' so i deleted the status and emailed him and he confirmed that my boyfriend did make that account behind my back? i ended the relationship b
