Hey Mark - I've struggled with this quite a bit, with my wife going away every other weekend.
Others may chime in here, but I would say, there's nothing you can do here that won't be controlling, pursuing. Don't let her see that it bothers you. I may be a hypocrite here, but I think the answer is to focus on you, get a life. This will 1) be good for you, and 2) demonstrate to her that you're not sitting home pining away for her, worried about what she's doing. Your life is interesting too.
