PLEASE READ SO YOU GET MY SITUATION


ok long story (hopefully short)


...i've known this girl since we were young teens
coz we were neighbors back then. we started out as friends (you know doing things for her like her assignments in school) then one day i suddenly developed a crush on her. she knew i had a crush on her. then after months or a year i finally admitted to her that i like her but she said she isn't ready yet (she doesn't have a boyfriend by the way)which of course disappointed me but i understand coz we both were studying back then. i did this two more times (coz she is somehow showing "signs" that she likes me) and she still said no so i gave up (but you know you don't really give up...just stayed low). so i dropped out of school (coz of financial difficulties and we were in college btw) and focused on my "career" and she focused on her studies and her work (shes independent). she sends me messages on facebook from time to time asking how am i doing but i didn't reply coz you know...trying to "move on". so fast forward 4 or 5 years later to this present day (with no communication although i see her on facebook sometimes)...shes finished her studies, i've expanded my career (and life). suddenly last christmas (2014) she PMed me on facebook asking me again how am i doin...i finally replied (coz hopefully i've moved on). so we catch up to things...then just this january i invited her to come to an event at our old neighborhood
and she said yes (she never says yes ^^). so at the event she did came and i was shocked coz i thought she was just joking...so we talked along with our old friends and neighbors...i was star-strucked coz of how she had changed (shes matured a lot -physically, mentally, and emotionally- but so am i) and my heart pounded again (i thought i've moved on?) so we talked and talked then i asked her if she had a boyfriend this past 5 years and she said she still doesn't have one (^o^) and she asked me back if i had any girlfriends and i said no/none (no really i didn't have any girlfriends this past 5 years)...the big difference about her now is that she now touches me (no not that kind of touch ^^) like slapping my arms and legs, pinching me, laughing and smiling with me, complimenting me ,telling me i've gained weight (i was skinny back then now i'm working out) you know that kind of things...(and i compliment her back)...so for me this is a new thing coz she doesn't do these kinds of things to me before...ever. and now since december we've been chatting on facebook like hell, at least 3-4 days a week...just casual chatting - you know asking hows her day, laughing over small things (shes always the one to chat first...no not really always...sometimes i just send her a smiley just to know if shes there...we sometimes even stay late just chatting but i don't overchat her or force her to reply coz i know she has work)...so anyway (sorry for the long story ^^)
this coming weeks (february) i'll be working abroad (i don't know maybe a year or 2 or 3...i'm still waiting for my flight schedule so there's no exact date when will i be leaving but it'll be in february)...i've been planning to ask her again to be my girlfriend (in a mature way of course and i don't wanna do it on chat or text, i want it face to face). i really don't know what to do...(i'm not really afraid that she'd say no but c'mon).

i've been thinking if i ask her now maybe she'll think i'm rushing it and i'm desperate coz it's only been 1 or 2 months for the past 5 years since we got together again (she knows i'm leaving btw and even joked about coming with me) and i haven't even asked her (yet) to go out on a "date"...

and if i don't tell this to her...it's years abroad man c'mon...(i don't wanna wait again for years man...were getting older ^^)

what should i do guys?
please please i need your serious help/advices coz i'm really leaving...
