Communication Please

Me and my boyfriend has been together for 6 months now and we love each other very much. He plans to marry me(have gotten approval from daddy n the fam), move in together, live life(like its golden). The thing that kills me is the his communications suck sometimes. Right now he lives about an hour from me so when he takes me home and it's late at night I want to make sure he get home ok. (All we mostly do is FaceTime). He'll get off the phone with me say he's gonna call me back and don't. He gets off of work at 3 sometimes earlier and I don't hear nothing from him for hours. Sometimes the whole night. He oftenly won't answer his phone. I sometimes think something is up but I don't want to think like that. I know he wouldn't do that to me. I'm asking for communication. I want to know if he is safe or ok.
