What the hell should I do?

I had an arguement with my boyfriend a few days ago. It was my fault. It was right before he went away on a ski trip. He ended up hanging up the phone on me. Well I sent him a message apologizing yesterday, he left on friday. I haven't heard from him since then. We were supposed to meet at his apt Sunday afternoon around 5 (today). This was the plan before the arguement. Well he lives an hour away from me so I just decided to come here hoping he would be home so I could apologize. But he isn't back yet. I tried calling and only got his voicemail, I left a message asking him to please let me know if he didn't want to see me. Since I didn't want to drive all the way there for nothing. I haven't heard back from that either He gave me keys to his place so I could come anytime. So now I'm sitting here at his place feeling stupid. I don't know if maybe he doesn't have a signal or if he is choosing just not to respond to me. I'm worried maybe he decided to stay another night..but would hope he would at least let me know something. I think most ski lodge places would have a singal for cell phones? Should I wait it out a little longer or leave? I'm so tired now and worried about making an hour drive as exhausted as I am.
