Does he have to tell her about every breath he takes? It's a molehill (if that) turned into a mountain of some substance.
There have been questions here, about his mental acuity, other illness he may be hiding, suggestions re relate, couples counselling, visits to Citizens Advice blah blah.

Being on here has made me realise that I'm so so glad to be free and single. Unaccountable to anyone, unless I fell foul of the law 

Does being married mean that, if you change your habits such as going out with mates on a Friday instead of a Tuesday and not telling the Mrs where you're going, you might be suspected of having an affair and/or, if over 60, having a mental illness?
I think it's a storm in a teacup, brewed and stirred into something sinister by someone who wants to know the minutae of another human being's life.
