I think I'm going to cut my crush out of my life.
Why are you thinking about cutting him out?
I don't think being with him would be good for me and it hurt's being around him.
Wanting to get away from emotional pain is completely understandable and when it's caused by a person of course it makes sense to get away from them. It's really good that you're realizing he might not be good for you and I hope cutting him off helps you move forward.
I hate this dude.
It sounds like you are a very brave person. You understand that this isn't the best situation for you and you are distancing yourself from it, that's very brave!
