i broke up with him

I feel so guilty for the way i treat him. I didn't even breakup with him because of anything he did, i just hate the person i am when i'm around him.

this sounds terrible, which it is, but i was talking to this guy(flirting) and i finally told him i have a bf. i told him how i don't like my bf but i'm not sure how to break up. My friends have been telling me for ages to break up with my bf but for some reason, i only ever listened to him. 

I feel terrible but i just don't like him. He kept trying to say things and find reasons for me to stay. I can't force myself to like him, it's unfair for the both of us. 

I hope he actually tries this time, I hope this was all worth it.
