There’s no way you ll ever know what parents or anyone else thinks whether it’s joy, false memories, fear, wishful thinking, or guilt You are making sure your childhood isn’t repeated by your parenting so that’s all you can do there is no value in constantly second guessing, what they think.
I believe you ve had counselling for your childhood but judging by all your posts you have never been taught how to move on That doesn’t mean you should deny your past or not feel sadness for the child within you but about you forming new memories for you and your children which I feel you ve done so why dwell so much on the past wrongs, rejoice in the fact that their wrongs changed you for the better
