Trying to get out of my funk

Hello. I'm struggling a bit right now, so I just wanted to jot out a quick bit and share really. Hopefully it'll give me some strength.
My life is in quite a bit of flux right now. In about two weeks I'll be going on a six-week assignment for my job back to America, and then after that I'll be returning to Japan, but with a lot of travel, before I finish out my contract at the end of this year. What this means for me is that there's going to be very little opportunity for me to meet a girl and really get to know her. I'm not one for one-night stands, either, though that's probably more due to the fact that I don't like going out and meeting strangers and trying to sleep with them. I like getting to know girls. For me that's the real fun of sex: being intimate with a girl that you really like and have been wooing for a decent amount of time.
I had a girl like this, and I'm still trying to get over her right now. We slept together about a month and a half now, and since then I haven't had sex. I'm a guy who typically does have sex, at least once every few weeks, and even though I know I'm not gonna get much sympathy from some folks, it's tough for me to think about going the next stretch without a special girl in my life. This girl, the one I mentioned, she called things off between us for good reasons related to work, and I respect her for being honest about it, but it still hurts to really like this girl and not be able to be with her. A part of me thinks I just need to go out and meet a girl and sleep with her, but at the same time I know that whenever I've had meaningless sex in the past I've always felt terrible. And like I said, I want sex to be special.
So lately I've been by myself more. And this has caused a lot of temptation for me. Well, not that much, honestly, but I can feel it building. I haven't looked at PMO in over 45 days now, which is my longest streak, but I had been masturbating thinking about the girl up until about a week ago, when I started to feel ashamed of it. So now I'm just over a week with no masturbation whatsoever, and I'm feeling pretty lonely. Sometimes I feel almost sick to my stomach, and I want to text this girl constantly, and really I want to move on with my life, and find a new girl, but it seems pointless when I have two weeks left on this side of the world, and then my life is going to be changing so much over the next year. Where will I find a new girl? Obviously that's a problem for me to figure out, but it's good to get some of this down.
Wish all you guys safety, happiness, health, and a life of ease.
