What do I do about him?

So my bf got busted at school for drugs and got expelled, broke up with me for no reason, and got sent to alternative school for the rest of the year and will be back next year. The only problem is that we were fine and I felt like I was on cloud 9 being with him. And he loved me.. Like he told me he had never felt this way about a girl and called me on the phone one night crying before we dated and we were just really close. Now he wants nothing to do with me I guess.. When all I'm Doing is being here for him. I haven't talked to him in almost two weeks and it's killing me. He's the only person I've ever really loved in my life and I don't know whether to move on cuz I know people change, or push through it cuz he's probably just under a lot of pressure?? Help!!!:(
