How to get over him?

First relationship and long term relationship relationship ended today. He's military and stationed far away from me. We met online and found we had a lot in common and eventually started dating. He got leave last December and we met in person and I loved spending time with him and him in person. Starting late January work got busy and I hardly heard from him. I'm in school and work at the theatre and with what we do we move fast. Even before we were dating I was fine with hearing from him middle of the night my time or Skype with him then because that's when he's off work. My classes are so fragmented through the day and I try never to schedule mornings for myself because I'm a night owl and was before meeting him. 

We started fighting because we would go weeks without Skype and he would take days to text me back. Finally after a while of trying to fight for something that worked for both of us I couldn't take us fighting and gave up. After that I told him that i was done fighting with him and that's not what I want. That was about feb 24th and no fights until two days ago when he blew me off for Skype and I told him how I felt and what I wanted for us and he said he would try and i was happy with that. 

He asked if I think we could get past this. I said yes. 

I asked if he thinks we could get past this. He slept on it then said that he thinks we can get past it. I told him that him thinking that made me happy. 

And it did. I really thought we could get past that. 

Then he skyped me fairly early his time and we ran out of things to talk about. He wanted to go to sleep and I never like saying goodbye to him because I really do like spending time with him. He then ended things. 

I really didn't see that coming. I thought we were going to be okay. 

He said its because if his work and how busy he is and he cant anymore and he doesn't like the way things have been. 

We were together 10 months. And this week I had known him for a year. 

What I really want to know is how do I get over him?
