My wife and I fight about 5-6 times a year
Most common Root cause is..
she thought we had firm plans and I was unaware or thought those were "maybe" or " Ill let you know if I can make it"
But if I say "no" or clearly rule out possibilities..
Way before deadline
then I seem inaccessible or absent or disinterested
There's really no solution except to navigate the best I can
The Dr Phil answer is to give her hour by hour updates but fukk that shyt

sounds "reasonable" (to a nitwit) but only creates resentment and turns fun time into a chore
We both like to socialize "as a couple" but 90% of when we don't go, it was me who couldn't make it.. And understandably that can irritate her
