<human>: Can you succinctly summarize the text in 1-3 sentences?

Boyfriend and I have been together for almost 4 years friends for 4 years prior. We are long distant b/c of college, but we see each other on breaks and have talked everyday of our relationship. The only thing we argue about is communication.  

This summer he's away on internship across the country. He doesn't have good service out there so we haven't been talking as much as we like. Upon until 2 weeks ago we talked daily either via text/or phone call. 

two weeks ago he texted me asking me whats up and thats the last I heard from him. I called him twice over the last few days and the last time I called his voicemail was full, which it never is. So I thought maybe he lost his phone or something happen to him, but facebook messenger says he's active every few days. I messaged him on there and the message hasnt been read though it says he's been online since. 

Not sure if he is ignoring me or what to do now. We didn't argue and were joking around like always before he stopped talking to me.
<bot>: No argument or reason, boyfriend stopped talking to me 2 weeks ago. I've called and sent him facebook message.  Facebook messenger says he's active though.
