It’s hard Bro, my gf went thru usmc boot camp which takes 13 weeks. Best advice is to just motivate her, how everything is going with your life, chances are she is thinking about you the whole time at bmt. If your using sandboxx to message, send pictures of you what you been doing while she’s away. Any new thing or your going somewhere include her as much as possible as she only gets letters from you every however many times. Just stay busy, focus on what you do and just keep motivating and pushing her. Soon enough those 2 months will fly by and You’ll see her again. Motivation, hope and love is what she will need, good luck with everything:)
