I suspect the logistics is not really what's holding you both back, but rather the finality of taking actual steps to move on. Even when it is clearly over, it is really hard to stop hoping that maybe the marriage could somehow be revived to something like its former glory. Everyone will add to that hope by pressuring you to make it work "for the children" and/or advise more counseling, accept that "good enough" might be tolerable, etc. It is really a difficult thing to finally separate. I feel for you. Maybe you both just need a bit more time to process what you want to do next ... sounds like giving it as much time as you need won't harm anyone.
