S, it makes me sad to think of the possibility of you losing your children. In a world where so many fathers walk away, it is not right.
I cannot believe that the courts will not see how wrong it is. Have faith that they will. This is one fight you must pursue. You have no choice. This is where you must put your efforts right now. Worry not about wife and where she is on her journey.
Keep thinking positive thoughts, keep praying and loving those kids.
You are in my prayers always, my friend. It will work out, it has to.
