Long Distance Relationship l

So long story short... my man and I have been together about a year and a half. We used to work together so we spent almost everyday together. Last year he joined the military in hopes for a better future for us. He's now in Japan and will be there for 3 years. We're struggling to find time to communicate. I'm waking up, he's going to bed. He's getting up, I'm sleep. When we do finally catch other it usually causes a fight.
