LDR Advice needed...

So, here's the thing. It's complicated.
We met on Tinder and proceeded to date for the next month. And it was amazing. All that butterflies and sparks flying crap was actually a thing, I didn't believe it. 
It's going fantastic, but a month later he texts me and says he got a promotion that would relocate him to Hong Kong for a year. He had three days to decide and less than a week to leave. He took the job. We had one more night together, deciding long distance would be dumb since we just met and I still had a year of school to finish.
But we kept messaging, flirting, sexting, and sending nudes and sexy face timing.
And moving past that, we emotionally have gotten closer, sharing our life. He's my number one supporter and he's so proud of how I'm doing. Around month three of this, I discovered I was in love with him.
But, we are technically not together. So I go out on dates, I hook up with others, so does he. We don't say anything to each other about it, and we are both jealous people, so for both of us, it's better to not know.
In many ways, I feel like we are both trying to move on, but we admitted last night that we aren't done with each other yet... although, I feel like I am starting to.
In a week, it will be 9 months, and it looks like he'll be gone for close to two years. Even then, we have no plans to be in the same city when he gets back.
This whole thing is so messed up because I want more and he doesn't want to give it but he doesn't want to stop talking...
So, how do I stop this? How can I make myself not love him anymore? How do I move on?
Tl;Dr this relationship is hurting and how do I stop or move forward?
Also torture, he's the best repeated orgasm I've ever had...
