Goodbye Boyfriend

So jeez idk how to even post this. I wanted to talk about it somewhere... Ive been seeing my bf for about 4 months and knew him 2 years prior. We've been actually "dating" for almost 2 months. He is the only guy who has ever treated me like a lady and is a gentlemen; also great bc he communicates beautifully and has the same interests. But i only have him till Sunday. Bc im leaving for the Army. Im so fucking heartbroken. I see him 2 more times then i leave ...for 4 years. He doesn't believe in LD.. and i get it. This really has me in so much pain.
