H's parents are, and always have been, very dysfunctional. They would not likely be capable or receptive to the idea. As someone else on these forums often says correctly, "the goal post is an ever moving target."

H has many more problems than just that, so even if that could be corrected, it would probably only have a nominal effect on his mental health at this point.

When we get to be adults, we need to self-approve and self-regulate. That's part of being an adult, which ultimately includes detaching from our parents, and not reattaching in a parent-child type relationship with someone else, like a spouse.

I don't know how old you are, or if asking a parent about it could be productive. It would depend on the parent and how receptive they are to a critique and self improvement. In H's case, his mother deems herself perfect, so asking about anything that looks like a shortcoming on her part would be met with anger or possibly rage.
