Thanks, brenalim...we have not separated before (guess we did for a good part of a week a good year ago but wasn't anything "formal").
definitely get the "not believing what she says" thing - told her point blank i don't know what to believe and not after 2 years of this and multiple times learning this is still going on (electronic contact and at some times even more).
just need to stick to my guns here and not let this drift back - am doing my best to get through our "last" holiday together as a family (potentially) but know this is the right thing to do.
had a good IC session today and also talked to my financial planner, so getting the funds and conversations going (including with a few attorneys that specialize in collaborative divorce) so we can come up with this separation agreement early next year.
