have you guys talk online a lot? my friend who is a pakistan deaf lady talk a lot with a hearing pakistan over online for a year or so. Yes they both are in an arranage marriage. SO WHen he visited USA to meet her in person for the first time, it takes some time to talk, just treat her just same what hearing person is except deaf. So all you can do is to use your eyes to watch her hands, body language and write on pen and paper back and forth then teach you how to sign for words. I hope you and her do talk a lot online so you both can understand each other then in person. it takes a lot of patience and pay attention to each other by body language or lips.
HOWEVEr i do not know if your girl knows sign language? does she speak ? if she speaks only then keep your face looking into her face, just facing her face so she can see your lips.
patience is the key. good luck!
