Hi SaltyDog, abandoning the family home to let her deal with the "crotch-goblins" full time would simultaneously reduce your chances of reconciliation and give you a lesser relationship with the kids (which would be notable in a D). If R is no longer as important to you, that latter consideration seems key.
If you re-take your home, you get to be with your kids 100% of the time, minus whatever time you/she chooses to go out for quiet time or activites, until the rental expires or she solves that issue.
