Go ahead and tell them. If that is all you did then thats better than most people I would think. The worst is not telling and they find out. Then you are denied a clearance in many cases. If you are close to the Smoky Mountains in Gatlinburg TN or can go to Vegas you can get legally Married in a Day. Then you can tell them you fixed it. Some states have common law marriages, You would probably have to look that up and ask a lawyer to be sure. NEVER LIE ON A Q. I seen a lot of people boned because of this.
