I live with my fiancÚ in Virginia. His car broke down recently so I've been letting him use mine. We had an argument last night and I specifically told him that he cannot use my car anymore and that if he did, I would report it stolen. I woke up this morning and both he and the car are gone. I know why he took it and I know where he went. Can I report it stolen even though we are engaged and live together, and even though he has his own key for my car?
