How come i can't forget about this jerk?

okk so lng story short oi met this guy who lives around me, and i think that he jus wants frm me soo i hvnt realli been tlkin to him. i'm trying to forget about him, but he keeps on popping up in my head!! and my heart jumps whenever i think of him. i want to forget about him soo bad, but i want to be with him too( which i know would be a bad idea). i even had to delete his number from my phone so that i can prevent myself from calling him or txting him.. how do i get him out of my dam head??? i dont want to like him :((
