A decade now.
I am 27 year old staff sergeant in the Marine Corp. Before I left for bootcamp 10 years ago I proposed to my best friend, who of course my girlfriend. She turned me down not because she didn't love me and want to get married but because I was becoming a soldier. Her last words to me were " I love you, and I would have loved to be your wife, but I couldn't stand to see you leave for years at a time, I'm really sorry." This was in 2001 I haven't seen or spoken to her since then buy I'm still in love with her.
