I deal with the same thing. My wife's language is quality time. That and physical touch. Kinda doesn't work when she doesn't want to be with her husband. Not really sure how to address this one. I guess the best you can do is try to make every moment of interaction that you have with her a positive experience. Or at least not a negative one.
Hopefully, she will spend more an more time back home and you can begin to rebuild the positive feelings she used to get when she was with you.
