You're going to be OK, you are OK, you've always been OK.
You're XH can say whatever, he has his story. You don't have to buy into it.
Keep writing your own story. Too often we get caught up in our past forgetting that every day is a chance to be different and we can let the past go.
XH is welcome to stay with his dated vision of you but you can recognize when he's doing that. Let it go (as your thread title says). You don't have to prove anything to anyone.
Brene Brown uses this quote by T. Roosevelt "It's not the critic who counts; not the man who points out how the strong man stumbles or where the doer of deeds could have done them better. [b]The credit belongs to the person who is in the arena.[b] Whose face is marred with dust and sweat and blood; who strives valiantly ... who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly ..." in her writing about shame.
Your H is not in the arena.
