Is the guy i like ignoring me?

I like this guy & we told each other we love each other the other night. We go back like 7 years. Anyway, he is ALWAYS busy & right now he is on tour. I sent him a message on face book like 6 hours ago saying hey and he didn't respond.... i can't help it but i want to talk to him all the time! I'm so in love. And i miss him so much. And i feel like, if he loved me like he says he does he would want to talk to me all the time, but then again he is busy! BUT he was on face book before so.... he got my message.... Did he ignore it? And just because he is busy, does that mean he loves me any less?
