Break ups

So me and this guy dated for a little over 3 months and the first month we were solid and hung out all the time. The second month not so much and then Christmas came and he ignored during our entire break and when he finally talked to me all he said was "I'm sorry but I've been busy".

Usually that wouldn't bother me but it did and I started to think about our future with me going off to college this coming fall and him finishing senior year. (He's 16 while I'm 17) so I talked to him about it and he wanted to know if I would wait for him. I told him no that I am planning on going to college and that was that.

On to the point though.... After he ignored me over break I started to think of him as just a friend and even brought that up to him. He agreed but said he wanted to continue dating. So we did. Well tonight o finally broke up with after about a month of thinking about it. I know that wasn't fair to him but I didn't know what I was feeling and I wanted to be sure.

I feel like I did it very horriblely cause we met at Arby's and we said hi then he just kind of stared at me like he knew I wanted to say something so I just came right out and said "I want to break up" and he mumbled out an okay. And I asked if he wanted to say more and all he said was "but I wanted more(with you)" we are both very awkward people but I kinda wished he put up a little bit of a fight. Even if he just got mad.

I feel like the way I did it was rude and that I probably should have done it a lot better... What do you guys think? Is there a certain way you should break up with someone when you're just not feeling it anymore?
