Often on SR the advice has been given to "play the tape all the way through." As many have posted about here, I also grieved the good parts, and the lost fantasies of what I wanted to be that never was...but I could not allow myself to forget what got me to the breakup point. I could not overlook that this ending was a chance for a new beginning for myself and my daughter.
Take your time, take care of yourself, don't compare your self or your journey with anyone else's. Each person's path is their own.
