Mopsey, Continue to focus on yourself and your children and yes, the future. Your h is a mess and the guilt is eating at him. Not surprised at what he said about the money being spent on him or you deserving better. That's the depression talking for the "poor me" self.
You handled the situation very well. Keep up the good work!
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.
