You are going to VA in one month... use that time constructively. Do what you can about GALing and rediscovering who you are and becoming who you want to be.
You have to prepare yourself for the possibility that her family is encouraging her to stay in VA, change is not only hard for her but they will be a long way from their grandchildren so of course they are doing everything in their power to make her being in VA easy. You can't fight them on this because no matter what you do it will be turned into "see, he wants to take you away from us". Instead you need to focus on keeping close contact with your children and reminding them every single time you speak to them that you love them and miss them with all your heart but at the same time you have to remain the Father, and resist the urge to become the Best Friend.
I applaud that you got a Lawyer, a very wise move on your part to protect yourself and your rights as a Father... she may be mad because you beat her to the punch or it could be that when you did it all became real. She made a statement and you took her seriously... when what she has done might not have really sunk in yet.
Keep breathing... keep strong and keep posting, it really does help to vent.
