Just challenge her Ken...

"Have you been doing your part along with me to keep OM away from our marriage and our children?"

She will say YES

Then you tell her

"No you haven't... I am NOT STUPID"

The Sep Order will be filed as soon as I am complete... You should be ashamed of yourself, and I feel sorry for children that have to tolerate your wrecklessness... THEY ARE INNOCENT in this mess... but THEY will be paying the biggest price

I really am dissapointed you can trash a marriage like this... I thought OM was bad enough..."

WALK away
