He got really bad at one point and told me he would kill himself. Then I called him like a hundred times and he wouldn't pick up his phone or anything so I freaked out. Finally he started talking to me again and he still seemed in horrible shape so I e-mailed his school's counselor and told him about his suicide claims on the advice of a trusted friend and other things.

He found out, freaked out at me for it, called me selfish, etc. He refused to talk to me for over a month and when he finally did he apologized to me. But, after that he slowly started ignoring me and now he has shut off almost every form of contact between me and him and it's been months. I leave him alone except for an ignored 'hello' every so often. Is there anything I can do to get him to talk to me again?
