If you leave your home for one night and then return it would not be abandonment, nor would that likely be a reason to have you removed from the house taken, by itself. In order to be removed from the house, your spouse would have to file a motion to have exclusive use and occupancy of the marital home if the situation is intolerable at home; or apply for a restraining order. Also, sometimes it just makes sense for one person to move out.
Otherwise, I would suggest that if you are going to stay outside the home for a night, then you should leave a number where she can reach you if there is an emergency. A cell number should suffice.
