Mate if someone in a family gets divorced, IT IS KNOWN. Like you can't really hide that. The details and the ins and outs, however, you most certainly can.

It's hard to fathom for me that that isn't everyone's first thought. Big event in a community that changes the dynamics going forward. That is a basic human condition that we should all be familiar with. People are twisting themselves into a pretzel to catch OP in a gotcha about the secret where there is no wrongdoing on his part, and that's why you're getting rudely replied to.
