I agree, the no back and forth/splitting of days will be ideal for your sons.

You have been an inspiration to the readers, not only w/the way you've handled you situation, but w/your growth, sage advice and your humor.

Keep up the good work and please don't be a stranger here. You are still part of the family even though you are blazing new trails in the world called life.

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.
