<human>: I've only ever had 2 gfs....one, I got engaged to obviously. I'm in the military and I'm just...sad. I can't talk to my CO about it because I'm not crazy sad...but I just need some help dealing with it for the next week. I'm on my phone so I couldn't read sidebar so I hope I didn't do anything wrong :(.

More info. It was a long distance relationship even without the military, but we saw each other every weekend or so. 

She was a recovering drug addict/party girl. I'm the stay in and game/write/cuddle guy...so we disagreed a lot. I felt like we just...I don't know how to explain it. anything was worth it to have a hug from her or see her smile...I'm just sad all that is gone. she left me because she saw her 2 year ex and said she loved him more than me. ouch.

Can you condense the text into three sentences or less?
<bot>: Kids get engaged, girl sees boy she was with for 2 years and decides she's happier with him than me. I am now sad. :(.
