If I got into it with my wife we might have a similar conversation.
Stan asked
"why put up with it ? Life's too short."
Well, I tell you that there is more to life than bickering over her religion. Since we have got older we realise how much we need a partner , someone to look out for us when all else fails.During Covvid life would have been hell on our own . She is a good woman even if she needs a little understanding and tolerance.
We could easily have split in times past but we are very glad now to have each other.
So.... I bide my time, hold my tongue , knowing she does not want to know I know. I have learned to let her be, and life is all the better for it.
