How has your life changed after ending relationship?

I think I'm scared to leave him alone, but I know that it is ruining my life. Relationship like that doesn't work and I need to be selfish, but I am so empathetic that it's difficult to completely cut contact. The thing is, I would like to stay cordial. Not friends or something but just be fine with each other, I want him to find happiness and get better but just without me involved. I just know that his reaction would not be so good.
