Why is it so hard to let go?

I don't have the proper answer, I just know I clung on with my fingernails even after our final split, (which I wanted too). The one explanation I have is that it was familiar and yet I'm not afraid of new things generally.

I sunk so low whilst in the relationship, I was reduced to nothing before I would give up and admit it was not fixable. After the final break I prayed to God for help in getting him out of my life and yet I would have still given my right arm to have had a different outcome. What is this all about? I never realized how determined I could be at self destruction, because I knew he was toxic, but still didn't want to let go or give up on us. I had maybe 1 percent half happy and the rest misery with him, so I just knew it was wrong. Finally I threw in the towel, gave up all my fight and accepted it was never going to be. It took me a long while to get there and I don't know why apart from being conditioned to expect nothing and feeling like I loved him more than life. It wasn't love, it was slave worship.

Why do we cling on, always hoping for a happy ending?
