Not sure I agree there... a friend of mine woke me up to this reality earlier today. My W has known these kids about as long as ours. Our kids go to the same school and my wife has taught there since my oldest was ~2. So she's taught their oldest.
She's in love with their kids about as much as him. I think I'm screwed in that dept. Although.. I know there has already been a chink. He ignored her one night while she was over there and she felt abandoned.
Do I go back to being friendly, or do I go dark for a while?
