Spare a thought for Huw Edwards family today. They must be going through hell and feeling deeply conflicted right now. This is something that will reverberate through their lives for years to come. And being such a public figure, impossible to forget or box away as a "family secret" (yes, every family has them) in the future.
I write from bitter experience. Some years ago my dad was similarly prosecuted and pleaded guilty. Completely out of character and out of the blue. Outcome was some sort of supervision order. No custodial or suspended sentence.
Fast forward today and my wife refuses to have anything to do with my parents, they are persona non grata to her, completely. On the other hand I refused to "cancel" my dad just like that. This has placed a huge strain on our marriage and mental health at times. To compound difficulties my sibling and their partner found a way to forgive. They remain very close to my parents and holiday with them and do all the usual family stuff Christmas etc. regularly. Watching that is very hard for me. (You'll notice I've written parents, yes they remained together.)
It's all too easy to join a braying mob ("peado!") but very very difficult for close family to navigate. There is no right or wrong answer and certainly no guidebook.
I'll leave you then with an open and hypothetical question. Suppose this happened to your father in law, seemingly out of the blue. You have primary school children. How would you react, and what would you expect your wife/husband to do? Really?
There is no greater test of your marriage than that (or indeed your relationship with you in-laws), trust me.
