I totally understand. The absolute worst part of being in this situation is having to leave your children. I will never forget the look on my DS4 face when WAH stayed at the house one night with him and I had to go to my mothers with DD11. There is no pain MORE excruciating. Sticking needles in my eyes would have been less painful.
Here is my 2cents. Your connection to your kids right now is imperative. You must remain in contact with them. No matter what happens in the M, you will always be there father. Not to mention, this is your connection to her right now. since she is going, you must focus on your parenting skills. It will be how she sees you changing. That is exactly what the DB coaches had me do when my WAH left in the beginning.
See if she is agreeable to scheduling visitation with the kids. Can you email her? Just ask for a schedule. No R talk. NO when are you coming home. Nothing but concern for your kids and when you are going to get to see them.
