If you do have an attorney, I recommend that you get advice from him or her on this issue. In general, if you spouse has established a new residence, she can be prevented from re-entry of the marital residence by the criminal charge of domestic criminal trespass. She could perhaps get a court order allowing her to enter the residence for a specific purpose, but you would have the right to notice of her motion for such a court order and the right to be heard on the motion.
