Alone and confused..?

treblemaker

So I’ve been dating the same guy for 6 years. We are long distance now but haven’t always been. We have always argued because we are both hard headed but we always make peace. However this last argument he just stopped talking to me. Did not try to fix it or anything. Anytime I bring it up or say anything he simply says he doesn’t want to fight. When I tell him we should talk it out or try to talk it out he completely ignores it or disappears. He has disappeared for as long as a week. I assumed my relationship was over but when I say that he goes “I never said that” or “your the only one who brings up breaking up” but he is not talking to me at all. How am I supposed to be alone in a relationship? And more importantly if it is over how do I move on without closure?
