In my case, at least one of the in-laws unwittingly provided cover for the A. Habitual weekend visits to her parents (both somewhat elderly) were so commonplace that I didn't really give it a second thought. I've since learned from WW that MIL had knowledge that something was up, and also that she kept a particularly big piece of information from me.
I'd never heard the FOO abbreviation until I found this forum, but looking at their relationship and domestic living dynamics, it's easy to see why my WW behaved in the way she did in certain areas of our marriage.
I certainly don't want anything bad to happen to them, but never having to see or speak to them again won't bother me in the least.Me: BH - 30s
Her: WW - 30s
Married - 2008
PA with boss for 5 months in 2013
DDay - Feb 2014
Separated, heading to D
At this stage, I'm basically bulletproof.
