So what did I learn tonight? It was a coparent evening with what my W considered to be fairness when the girls are involved.
and it was just that. Co-parenting. Don't read anymore into it. Christmas is a fairy tale for children. And the two of you have allowed them the fantasy of a family together for the holidays (somewhat). It is a good stepping stone for when reality hits a few weeks/months down the road. As, Elliot said, "April is the cruellest month."
And as for my comment about standing up to 25, there was no disrespect towards her, you, sir, need practice standing up for yourself. These virtual 2x4's you are virtually beaten with, You need to starting saying; "Look, I am a man. I make my own decisions, I know I am right for myself." Confidence, decisiveness, self-respect. Go back and read your million posts and what you have told us about your wife.
Stop being walked all over. Stand up for yourself.
When the holidays are over and things are back to the way they were/are/gonna be it will be the most important thing going for you.
