To me, the only reason to do that would be to keep starvation at bay or to keep my home and even the home is questionable. My children need me more than they need toys and so does my wife. And I need them more than more toys or fancy cars and TV sets.
A marriage relationship will suffer greatly through such separation and the chances of it ending are simply too great.
My family is more precious to me than almost anything that extra money could buy. A few months away might be acceptable (move the family to me ASAP?), but a long term separation would definitely not.
