Welcome to psychcentral jewels; you've come to a good place in your life!
Yes, I agree, you need some closure. Did you ever see the scoop on that lady that allows divorcees to smash their wedding rings and make a different item from it? While you probably don't need that, you do need to work out, for yourself, what happened, what you still feel responsible for, what things you had/have no control over.. so you can move on with your life and not feel guilty or any way bad from the past.javascript
