It is also not grounds for a protective order that would remove him from the house.
If you file for divorce, Va. Code 20-103 would authorize you to seek "the exclusive use and possession of the family residence during the pendency of the suit."
No. Contact a local attorney that handles divorces and make sure that you will be considered separated when living under the same roof. Some judges do not consider this to be separated. You must be separated for 1 year or 6 months with no minor children and a property settlement agreement for a no-fault divorce.
