I think you should make sure if he likes you or not. Maybe even be straight forward and ask him. Cutting yourself will only hurt your body , the body who loves you alot and is with you everytime.
And if the guy doesn't like you, move forward. Easier said than done , I know. I mean who likes to be rejected right? But we can't control our feelings.
I hope everything turns out great for you, and like I said, if you ever need someone to talk to, I'm right here :)
