Aussie Promotion

MY girlfriend recently left for 6 months to Australia on Semester Abroad. We have been dating for 16 months. We are both 23. She seems to be very much in love with me as I am her. I go out of my way every day to make a point that I am always thinking of her. She is the opposite really. But what I am concerned about is…
She recently changed her facebook relationship status to take my name off of it, although it still says “In a Relationship”. i asked her why. she responded with, “i dunno i was drunk.” i asked why she didnt just change it back per my request on facebook. she said, “i just dont want people over here to be that much in the know about me”. and she leaves the conversation to go camping with a bunch of duds. interesting, what do i think of that? pretty shady huh
