I can understand your feelings. And I, too, even very recently with my wife had to negotiate some potential mediation terms with the thought in mind that if I fought her TOO much, the alternative was that she could hire an atty, and get much, much more. So that's a practical reality.
I'm not a big believer in separation, however, unless the home situation is abusive or COMPLETELY toxic toward the child(ren). Too often, an S is just a precursor to D, and it doesn't give the LBS the opportunity to live out your "New Improved JKL" in front of your wife's eyes on a day-to-day basis.
