Ironic. In my sitch, it was the presence of kids that led me to so much appeasement of my wife.
It didn't work for me either.

I dont normally reccomend softball, but when there's so little leverage and her own father is enabling her escapism I am going to stand by the softball approach. OIN you have a history to UNDO here... and hardball when there isn't apparent cause to use it right YET is not helping you.
A phone call from a man does NOT equal an affair.
Save hardball until you are confident she's cheating. One call isn't evidence of an affair.
