I've been there....done that......wife # 2 didn't listen.
She had to find out for herself. It was part of her journey too, I guess.
Who was I to get in the way of her learning experience here on earth?
If she wants to know....if she recognizes the red flags.....(or the parents).....they will be seeking information on their own.
I can sense that you don't see what the rest of us do....but, you need to drop out of the crazy cycle.
