you're allowed to vent and when she brings up the settlement, just tell her that getting a divorce settlement doesn't mean you're going to get rich, more times than not, you're going to end up with less money then expected and a pile of expenses on top of that to deal with. Consequences for the choices made, sucks to be her.

You didn't "talk her" into anything,
if you had that ability you would have prevented the divorce by talking her into working on the marriage so her excuse is just bull$hit, and you can tell her that too.

If anything tell her you think she got too much :-)

Yes her feelings and responses are coming from an emotional place and yes it's not logical, she's the WAW, expect it and smile!
