So the response I got from a lawyer was that W can file for divorce in the state she moved to in as little as three weeks, and the lawyer is urging me to file soon in my state if I want jurisdiction here. I don't see how it matters much where it is filed, other than if W requests a temporary order for custody that I would contest. And I would probably have to find a new lawyer, but that's not a huge concern for me right now.
Feel like I'm heading into battle today. No running away.
