So... you want to unhappily co-parent? You want to be adversaries? How would that affect your son?
This is where detachment is really really important, I think.
I think Wonka's message is awesome . Though I wonder if that last bit comes off as controlling: "don't talk to me like that"
You can't control what she says, but you can tell her that you find it insulting when she says that. A subtle difference, but maybe important in this case? I dunno. Curious what others think.
