Witness protection program

My character is a key witness to a major crime. Maybe she is left for dead but survived. While in the hospital an attempt is made to kill her. The DA decides that she needs to recooperate in a safe house, one far away. Your character is set up as her husband, and you are her bodyguard as the trial has a year or so before it comes to court. You are to care for her till she is well enough to care for herself. Then you are basically protecting her. But then her cover is blown and you have to flee and go off the grid with her in tow. Keeping her alive until the trial can start.
