How to get over someone who broke my heart?

He hurt me so much. When I talked to him about the things he did that hurt me.He used everything I said to let me know he still loves his ex. He made it painfully clear that I helped him realize he treated her the same way and that's why she left him. He was so full of regrets,not for breaking my heart, but for realizing why she left him. He makes excuses for her but blames me for everything.

After things didn't workout the first time, I was determined to move on and let him go. But what did he do ? He held onto me only to break my heart once again. I admit it's partly fault because I was too weak to walk away.

I wish I could hate him for what he put me through, if I could direct all this pain,anger, disappointment and worthlessness towards hating him, maybe I could get over everything.But I can't do that. Instead, I pray he finds peace and happiness

I find it very frustrating how I can have so much love and empathy for someone who couldn't care less about my feelings. It's hard for me to accept that I care so much while he doesn't care at all.
