Ok, then that was my suggestion.
I happen to understand the concern that the mother has, and how it can be troubling.
I also think it takes respect for the son’s privacy, while at the same time, expressing concern and support towards the son.
I happen to think that there is a certain level of “control” by posters here, who are trying to control the relationship in a manner which does not open itself up to healthy communication.
The mother did use the phrase “divine right”, however, she used it in this manner,
“It is my divine right and duty to guide my children and lovingly correct them so that they stay on the path of righteousness.”
She did not say it was her divine right to demand that she knows their reasons. She only expresses she hope’s it’s not contraception, and she is asking whether it’s her place to ask.
I have offered my advice to ask about having a baby in general. This allows the son or DIL to share what they wish, or dont share, without accusations.
This allows the mother to acknowledge the elephant which seems to be present, while respecting not to pry what does not wish to be disclosed.
It’s not unfair for a mother to have these concerns. They need not be demonized as toxic.
So my last post here (unless the OP responds to me) still maintains that I think it is healthy communication to ask about a baby. Whether the mother maintains prudence only depends how she handles the response.
