DD, get your ducks in a row, know your rights, think about custody of the kids in the event of D...it doesn't mean you'd file but it will prevent you from panicking in case your W choses OM. Usually the first 30 mins of consultation is no charge.
I have and I'm prepared for either scenario. It also gave me the confidence every time W mentions D. I had told her she's free to go, opened her cage. i told her i wont stand her way of D.
More wisdom. ^^^ This (getting legal and financial ducks in a row, just in case) is NEVER a bad idea. Don't tip your hand to your wife -- just do it. And "hide it in your heart," as the Good Book says.
