One year in but a newbie

^^^^sounds like she has a financial problem(s) as a result of leaving. this is not your issue/concern unless you choose to make it that. I personally would not live under the same roof as my STBX or estranged spouse (however you want to see this)unless we were working on the M and there was NO ONE ELSE IN the M at that time. Your kids are old enough that this would be more confusing (IMHO) than just staying apart.
