Why do i feel like this?

I'm in love with this guy, but the thing is i don't wanna go out with him because im scared of commitment... (Its like when my heart goes fast and that scares the **** out of me i don't know why?) Also i have trust issues because i find everyones a hypocrite and everyone lies... like i know its not gonna last me and him... if we go out all will be waiting for is to be tired of each other... i find love stupid, and who says hes not cheating on me? Why do i feel like this?
