Trc2009, sorry you find yourself here. Generally it's not a good idea to move out of your house in these situations. You should consult with a lawyer to determine what your best course of action should be to protect your rights just in case she does file. In some states the spouse who stays in the house can claim abandonment and use that to their advantage in divorce and custody proceedings.
Other than that, yes, you should disengage and give her space. She's asking you very specifically for space right now, but you are hesitant to give it to her because you're afraid if you do, she won't come back.
The reverse is actually true -- if you continue to pursue and try to control things, you will drive her farther and farther away.
Get the "Divorce Remedy" book and read it. The shortest path to reconciliation for you is moving the opposite direction and giving her MORE space than she is asking for.
