Why do I feel so guilty?

I was talking to this guy for about 4 months and then well we had sex because I felt ready and I felt that I could trust him. I knew him for about a year but we didn't see each other for about maybe a little over a year. Anyway, after that he called to see if i wanted to do it again and i said no because I didn't want it to be just that. Then he got mad. I'm not sure if was the fact that I bruised his ego because I didn't want to do it again. (it was my first time btw and i'm about to be 20). Anyway, after that he was just being an *** to me by not answering my messages. I wasn't even being needy about it but it was bothering me that he was acting like that. Well i broke it off because i felt like he wanted to control me in a way and i didn't like that. But I feel guilty. Why? I feel like he wanted to toughen me up a little because I was really sweet and I guess he perceived that as me being a doormat which is not true. I feel like its ok to express feelings. Why do i feel guilty

Well after a month all he said to me was "hi" through a text message and when I responded. He didn't say anything. it's like he wanted me to be on his ish. Well i had to think about it and the next day I told him to F off basically and blocked him. It's been about a little over a month since I've had any contact with him but I feel guilty and I guess I still have those what if's in the back of my mine.
