How do you stay strong during No Contact when all you get is urges to contact him?

He discarded me even though I stayed after all the cheating, mental and physical abuse. I miss him and love him still. I feel so stupid for struggling to let go. He blocked me and I still can't bring myself to do it also even though we haven't spoken in a month. Does it get easier? I think about him constantly. I don't want him back but I feel so rejected. It's like I want him to hoover so I can feel like I was worth something to him. What is wrong with me? Please help!
