Hell, third time lucky, maybe!!!!
Anyway, very quickly because I'm tired.
1. I agree with jakki I think he's just using you
2. having had a five year relationship with an army guy I wouldn't ever read anything into having sex with an army guy - it doesn't mean all that much to them
3. I would take advantage of the time that he's away & non-contactable to find someone who likes you for you and isn't playing these games.
