So...since the beginning of this school year, things have been pretty rough, for lack of a water word, and one of my few friends i made at my new school became close to me very quickly. After hanging out with him for a while, we went out a couple times, to which he thought that meant that we were dating. Because I'm a total idiot and like a puppy following anything it can, I simply agreed so that no drama would be caused. Instead of us getting closer or anything, he just became clingy, yelling at other guys ( who were/are my friends ) who came near me. I like him, yeah, but just the way he acts sometimes isn't exactly..."cool."
So...getting to the point, I want to break up with him. The problem is that I'm a total flake. I chicken out at the last minute, or just lose what i was going to say. I still wanna be friends with him, but I'm too scared that he'll get angry and we wont have any relationship at all. I can hardly ask a teacher for help, so how the hell will I tell him about this?

You cannot control how he feels when you tell him you just want a casual platonic friendship. His feelings and behaviors belong to him.

I would tell him that you don't want to go steady with him or anyone right now and you do like him as a friend but you aren't ready to go beyond that at your young age.

Do you have mutual friends so you could go out as a group until he accepts this?
