I need help with a very confusing ex boyfriend?

My ex and I have been talking since September. We have both liked each other since the first days we met but were too scared to admit it. One day, he asked me for my number on Facebook and we have texted each other all day everyday since that day up until about three weeks ago. In November, he asked me out and I said yes and we lasted until mid-February when I broke up with him because we didn't get to hang out as much as I'd like. He was upset at first, but we still continued talking. In March, we started talking like a couple again. We both still liked each other very very much but for some reason we did not go out. When track season came, we got to hang out every single day after school and it was great! I realized that I made a very big mistake breaking up with him and I admitted that to him. We started hanging out a lot more after school again. We would always hang out either at my house or his and all we would do is cuddle and kiss and laugh and smile and I really loved it. I felt like we were the perfect couple and it was during this time that I got very strong feelings for him. One day we got into an argument because he had told me he was going somewhere for an hour but instead, he was gone for the rest of the day. It worried me because I did not know if he was okay or not and I got upset that he did not tell me. (We were both very clingy to each other). Then for the first time ever, he started snapping at me. I told him I was sorry for getting upset at him and that I just care a lot about him and he said, "Every time I try to do something I like you make me feel bad about it!!! I am not your slave!!!" Or something along those lines. I feel like that is when the relationship started to fall apart, and I did not want that. We made up the next day, but the next week or so he texted me out of the blue saying that "he can't do this anymore and that he needs to end it." I was very confused and upset, and I gave him some time to think about it. When he finally texted me back, it was very clear that he was just as upset as I was and I invited him over the next day to talk about it. At first, we just hung out as friends but then we sat in my bed and cuddled again. He told me that he made a mistake and that he regrets doing what he did, and we both started crying. He wiped the tears from my eyes and told me that he was sorry and that he loved me. About an hour after that, he told me that he made ANOTHER mistake and that he needed to go to think about things. I was upset again, but later on the same night, he texted me again. We talked about that and he said that I showed him something... that I care about him a lot and that he made another mistake -__-. We went back to being an unofficial couple. A week or two after that, I invited him over again and we cuddled and kissed and acted like a couple, and then I asked him if there was any chance of us getting back together. He said "yes" and I got very excited. Then we talked about getting back together, but his mom came to pick him up. Right before he left, I asked him out but he said to wait because of everything that was going on in his life (college apps, his track season, death in his family, schoolwork, etc) and that he was not ready for a relationship yet, I got a little upset but I would wait for him. The following night he told me that he was going to prom with this girl that he used to talk to because her date had left her suddenly because of family problems in Puerto Rico. They went as just friends, though. I got upset because first of all he did not talk to me about it before saying yes, AND he was keeping it from me for a couple of weeks! I got mad at him, and tried avoiding him the next day. But then I decided to go up to him because he was acting very differently and I wanted to know what was going on. It was then that he told me that he can not handle being in a relationship and that we can't be anything more than friends. It crushed me, because I really like him and care about him. He said that "we might get back together in the future, but not anytime soon." I really want him back, and I really need some help doing that. It has been about 3 weeks now, and we are only texting a little bit during the day, and we still see each other in school. I asked him to hang out a couple of times but he turned me down because he had other plans. The other night, I did not text him at all and at night he texted me "Why end the streak?? I just wanna say goodnight! Hope you had a good day" Also, the other day he came up to me in the hallway and we talked and he gave me a hug, the kind when you two just hold onto each other for a little bit. I am very confused. Do you think he still has feelings for me? Should I just give him time? Should I try the "No Contact" things? Do you think that there is any chance of us getting back together? Is there anything I can do to get him back? Any advice
