Late last night i had a dream and she was in it again!

So there was this girl in secondary school that i was crazy about we were really close and i was in love one day she came round we were snuggling and making out basicaly what any young couple would do. Then afterwards a few days later she decides to go silent on me and tell me that she dosnt love me in that way and honestly speaking that really broke my heart. since then i have moved on to college (started September 2012) and moved back to uk (army school in germany) and at least once a month she has been in my dreams. i honestly thought i was over her but now i see her on facebook as well as my dreams i feel really weird as if i am asking myself what to do. truth be told i still have feelings for her and would probably date her in a heart beat because i have been single all my life (im 16) and am sick of being lonely. I just want to know what these dreams mean?
