What should I do?

So I met this guy on Tinder about 3 months ago and we have been seeing each other but not exclusively in a relationship yet. He went back to college a few weeks ago an hour away from where I live and lately things have not been the same. In the beginning, he was all about me. His effort was amazing and we would talk all day everyday. We also used to hang out practically every other day. There was never a dull moment. But now things have changed. We haven’t saw each other in person for 5 weeks. I don’t have a car yet so he has to come to me. I get that he’s busy but he hasn’t made an effort to come see me at all. We barely talk now and our conversations are so dry. Idk what to talk to him about anymore because I’m starting to lose feelings for him. I’m not interested in pursuing a relationship with him anymore. He insists that he’s still interested in me but that’s just not the vibe I’m getting from him. I tried talking to him about how I was feeling but he completely disregarded my feelings so I stopped expressing myself. My question is should I just cut him off and stop talking to him? I’ve grown to care about him and I really don’t want him completely out of

My life but I don’t know how to detach my feelings for him if I continue to still talk to him everyday. He’s a great friend to me, I just don’t think we are meant to date. What should I do?
