Need some girl advice

Have been seeing this guy who I know I'm too good for purely because he treats me like absolute shit and never sees me and sorta just thinks I'll wait around. I just continue to go back to this guy and I can't help it!!!! I mean this guy never wants to see me and just wants to talk on fb ( he never said it but just never asks to hang out ) and I can't handle that yet I reply to every message and think about him all the time. ( we work together so we see eachother there and stuff and we use to see eachother all the time. ) I need advice to get over this guy because my heart is slowly breaking....
