Just found out she already filed

Romeo...Gardener has it right about your words NOT penetrating the stbx! It falls on deaf ears and then it may make her fight nastier. She can find a way to use it against you somehow, too.

Vent here and try your best to keep the business questions emotionally void. She will be expecting you to get all angry and nasty so try to get some satisfaction in knowing that
1) you have self restraint
2) you are taking the high road (for your daughter, for your daughter, for your daughter--it is how I have forced myself not to flip out!)
3) you aren't giving her any ammo to use against you,and nothing to fuel the fire!
