Am I holding on to my abusive ex?

My ex emotionally abused me for almost two years. When we broke up, he pleaded me to come back to him but eventually I guess he lost hope and I heard he was flirting/dating another girl. After so much pain and proof that he has issues, I still have this part inside me that wants to help him, help him realize and get help for his emotional abusive tendencies.

Why am I thinking like this? I should hate him, yet I still want the best for him. Is this me holding on and having difficulty letting go? We live in a small city, I can’t move away or pretend he doesn’t exist. What can one do in this situation?
