I asked my W that one time a few weeks before she filed. I said, "Are you TRYING to drive me away?" She replied, "I don't know. Maybe I am." That was certainly how I felt at the time.
My Sister told me to let W to be the one to file so if the kids ever looked it up when they got older, they would see that it was her.
I don't know what to tell you Barkley. Sorry I don't have better advice.....
