Oh FIB, I am sorry. Sorry for your children and for you. It just all stinks, all the way around.
The only thing you can do is be there for your children. And pray that someday you and your wife will be able to develop a warmer, more compassionate relationship so that the children will heal.
My friend, you are going to have good days and bad for a long time. Eventually there will be more good than bad. This is my wish for you and yours.
