That's very good. Clever. W would immediately parry and riposte, however, with "this decision is because of you," which would have me on the validate-defensive, no?
"Silence is one of the hardest arguments to refute." Try saying nothing. Let her thoughts fill the space you leave. You've got this volley going back and forth between two very bright people with an incredible arsenal of comebacks - what if you just did NOT HIT THE BALL BACK INTO HER COURT? What if you just let it bounce on your side and not play? That would be a 180, no?
Be clear. The decision to leave is hers. The hurt she feels which brings your marriage to this point is owned by both of you. The OM - she owns that completely. These are the real property settlements. The more you argue with her, the more the argument itself becomes the issue...and it's really not.
Defensiveness = never a good idea. Root word of validate = valid.
Use good sense. Cheers ~
