I've stopped trusting my W many months ago... I now know whenever she says she's got "work" to catch up on, she's more than likely spending time with OM... working late, working on weekends etc...
It's more or less at the point now where she just doesn't say anything.
PacLove, I can relate. WW has always had 2 days off on her schedule. So when she says I can't watch the girls on her days off because she is scheduled to "work," I know she has plans with OM. First time, I confronted her and she denied, denied, denied...eventually own up to it. Now more than 3 times, I stopped confronting her.
