Hey Captain ~ I'm going to nitpick a little bit -- that was not really a DB conversation you entered into there.

Her: I'm never getting married again.

You (alerted to the fact you are getting sucked into an R talk): I'm going to go <insert GAL activity here>.

She's got her version of reality. The more you debate, question, defend, etc., the more she will entrench herself in her position. It is counter-intuitive.

When it comes to hashing out terms of a settlement, of course, it's time to assert yourself.
