AS, decided to make a quick stop by the boards today to say hello and Happy Thanksgiving.

I believe you did the right thing by being honest, but these are things I sensed by reading the message:

1. There's no enthusiasm to reconcile (doing it "for the kids' sake.)
2. There's a hint of accusation: "you never went through it yourself, so you don't know how devastating it is." This is likely to place your W in a position of defending herself--and she'll stop listening.
3. There's a threat: "I will never consider reconciling after that."
You already sent the message, though, so you'll see what happens next. I know the way she's behaved in the past, so I completely understand the way you feel. Continue being a great father and taking care of yourself. Take care, AS.
