What is wrong with him?

I have a serious question. My boyfriend, Jason, just broke up with me 5 days ago, and It is tearing me apart. Here are the details: We started going out after I had just gotten out of a relationship that was falling apart and was agreed to end on both parts, so it wasn't a big deal. Jason is a very shy person, and he gets nervous easy. He had never had a girlfriend before, so he is new at this. We go to a small school and we both live in the same area and are friends with the same people. He is a sophmore and I'm a freshman. On the 3rd week we were going out, he went hunting for a week. We weren't having any problems before this time and everything was fine. I told him I didn't want him to go hunting and leave me, but I also did want him to have a good time. I saw him the next monday at school, and we talked alot that day about serious things. He was happy to see me. We talked about his family and how he was thinking about dropping out of school and going to the army, or just getting a job, and he said he had been doing "a lot of thinking about that stuff" I just listened to what he was telling me. We never really got to ever sit down and just talk about stuff, you know? He said he didn't know what to do about his pick-ups either, and that was about it. He used to be on drugs, but he got off a few months ago, and he talked about that a little bit, and how his cousin is still having some problems with that. It meant so much to me that he was finally opening up to me. He went in the gym to play basketball before my game started, and my cousin came to get me to go to my house to get my basketball stuff, I asked Jason if he wanted to go, and he didn't want to go. I begged him about it for a few minutes, and then I said okay, fine, and I kissed him and left. I was okay that he didn't want to come with me, no big deal. So, I came back to the gym, about 15 minutes before my game, and told him that I was going to go get dressed into my uniform. I knew I would be able to talk to him after my game, during the Varsity's game, because he said he was coming to my game. So I went and got dressed, and then when we were warming up, I never saw him anywhere. He was with one of his friends. After my game, I still didn't see him, so I figured he had left. I thought that was kind of weird, but I wasn't the least bit upset at all. My Mom came to the game that night, and she was so high from narcotics, and everyone saw. I told my Dad to take me home. I was very upset about that. The next day at school I didn't have time to talk to him before lunch, and then one of my friends who is in his class gave me this note, and I read it and it said that he didn't have feelings for me anymore. He wants more time to himself it said. I couldn't take all this. My Mom's drug problem, and now this. I went out of class to talk to the counselor about all of this, and then she said I could go talk to him, so I did and I asked him why he all of a sudden...with no notice, just didn't want to be with me anymore. He said it was because he wanted to be with his friends more. I told him that my Mom was on drugs and that I couldn't handle this right now, and he said listen, I like you and I like being with you, but I think I'm going to have to break-up with you. I told him are you sure? because this is not what I want. And he kept giving me these looks of uncertainty. Like he had to break-up with me but didn't want to. I have been through hell these last days. I tried talking to him again, when I should've just left him alone, and he told me the same thing. He just want's to be friends,and that this isn't my fault, it was his choice. He told my friends that he likes me but he doesn't want to go out with me. He said that having a girlfriend is too stressful for him. I don't understand this. He had time for me, and we don't have to be stressed out all the time and all serious. I love him and I want to be with him more than anything. I have talked to several people who I told them to talk to him and find out why he made this decision. I can't chase after him anymore. He needs to come to me if he wants me back. No one can do anything, so it is up to you now. He is a Leo,and I am a Gemini, and the my name means "consecrated to God" and his name means "healer", if that info helps any. I am so depressed. I can't sleep and I can't eat. I need your help. What is going to happen with us? Is he hiding? Is he to stressed out about his future? Will he come back to me? Please, anything will help.
