What is WRONG with him? PLEASE HELP.?

basically, this guy and I had been talking for a little while. he was really flirty and on thursday he took me out of cl, held my hand, and kissed me... it freaked me out because I wasn't expecting it and he totally tried to jab his tongue into my mouth. Afterwards I was kind of overwhelmed. Today we were supposed to hang out but we ended up talking. He told me that he ****** up and he didn't want a girlfriend and just wanted to be friends. I told him I felt the same because I really don't care. I asked him what changed his mind and he got really defensive. In response to all of his defensive texts about how I was "trying to make him feel guilty" and how I would "talk bad about him to everyone at school" I told him that I didn't think badly about him at all and that I was cool with everything. Then he would shoot right back that I was making all the stress in his life worse and pull a total guilt trip on me. I would repeat that everything was fine again and he said that because I was saying it was fine I was signifying that I was upset. The only thing that is making me upset is that he is being so dramatic about this. I'm fine! I don't really give a sh*t about it anymore. I want him to chill the eff down. what do I do?
