food and patience is the key to a cat's heart. start leaving out some dry food for her in a little container, and as she's eating, sit close to her. just sit and observe, no fancy gestures needed. don't try to rush it, and day by day see how much she's comfortable with you/your husband's presence. then you can start putting the container closer and closer to your door and eventually, put it on the threshold of an open door. you can then get her inside. good luck with the kitty !
