One more thing, since your sons are still young and school, you may want to negotiate living in the current house until they have graduated from high school. However, that may not be something you want to do, so discuss this option w/a lawyer as well.
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.
