I know you're doing what you feel is best for your children. That's all anyone can ask from a parent.
Personally, I understand and support dropping the rope and moving forward with your life. You've shown amazing patience and fortitude over the past two years. And I think there's still a chance your W will take notice now.
As Puppy says, pray for the strength and courage to do what is right in every situation.
Hope you have a good weekend and some fun plans with the kids!
