What happens if a husband own a gun with a felon wife?

My husband and I moved to another state for work after getting married in February 2015. I have a few drugs felonies, nothing violent, from 2001 to 2006. He purchased a gun here, for protection of our family. As we had someone enter our home while we were working (a lot of the places around us have had similar break ins and robberies), he was reviewing safety and scenarios if I was attacked or burglarized at home while he is not here. Only then did it occur to me that if that does happen and I have to use his gun to protect or save mine or my daughter’s life, that I could be charged and put in prison. He says it ‘s his, not mine, and that no one would charge me if someone broke into our home or attacked me. But I am not sure and considering this recent compromise of our home safety, it’s really weighing on my mind. I am losing sleep. I am truly afraid this might happen, so please any help would be very much appreciated, and time seems of the essence. If there’s nothing I can do, what should I do if something like that happens? Telling them I’m a felon isn’t going to keep me or my daughter safe, and 911 would never get here fast enough. Also, if anyone knows if I can get a passport and voting rights restored? All my stuff with court, parole, fee and fines is complete, but pretty certain that expungement isn’t going to happen with 5 drug felonies no matter how much times has passed.
