<human>: Can you provide a brief rundown of the text in within 3 sentences?

Hey everyone! Thanks in advance for the advice. 

My boyfriend and I just recently celebrated our 9 month anniversary. Our relationship is great. We have little disagreements here and there, but we communicate our feelings fairly often. He positively turned my life around and I can't imagine being without him.  

For about 2 months now, he's been bringing up the idea of joining the Army (he's interested in Human Intelligence). It was his dream of joining the Air Force, but was rejected due to a misdemeanor he committed when he was 17. He has been talking to a recruiter and bringing up the subject more than usual. My boyfriend decides to leave once he gets his Associate's Degree which will be in Spring 2015. However, he says its still not set in stone and that I'm the biggest thing holding him back since he doesn't want to leave me. 

Before my boyfriend came along, I was seeing someone who eventually left for the Marines. We weren't exclusive, but I was deeply in love with him. I wrote to him during his training and we spoke everyday after. I was very lonely and had relationships the first year he was gone...

I'm scared to be left again and even though I support my boyfriend's decisions, I don't think I'm emotionally equipped for the military lifestyle. I'm wholeheartedly committed to my boyfriend and wouldn't want to be with anyone else. 

I need advice on how to prepare myself in case he does decide to join. And I want to know the good, the bad, and the ugly that comes with being a military girlfriend/wife...
<bot>: My boyfriend is considering joining the army, I've been left before and I'm not sure how to feel about it.
