What should I do? I havnt really heard from my boyfriend in almost a week?

My boyfriend is in the military so its not un normal for me not to hear from him for days at a time but ive noticed hes had plenty of time to update his facebook status multiple times a day and havnt even sent me a hello text. About a week n a half ago he said that he feels bad for me waiting on him to finally return home. We talked and decided we cared to much for each other. Every thing was great again untill 5 days ago when he started ignoring me. Does he want to end it? What should I say to him? Should I end it? I have deep feelings for him :(
