Sweetbriar, You have to have faith. There is a very good reason that God has put him on this particular path. He was broken inside and he needs emotional repair.
I know that this is very difficult, but you have to turn the focus back on to you and your children. There's nothing you can do for him except let him go to find himself. It's important that you children have your full attention as they need help in understanding that what their father is doing has absolutely nothing to do w/them or you. It's his problem, no matter what he tells them or you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
