Ghost of a boyfriend 👻

.
My boyfriend and I have been together for 7 months now, but it feels like we've only been really together for 5... He never makes an effort to reach me through my phone, and when I text him it always takes hours for him to reply (with short, to-the-point messages). He goes to a different college about an hour away, and he's not allowed to have a car so we never see each other that often. Last time I texted him something short and sweet for Labor Day ending it with "love you!" And he never responded or texted. 
It sucks because I love him, but I think I can get the message loud and clear through his silence. I texted him last night to ask when I could visit him next, because I feel like a talk this serious should be face-to-face. What should I do? Should I try to confront him on it or should I just stop wasting my time and dignity?
(We're eachother's first everything, so this is why it's so hard.)Â
