When he ignores you

Been going through a lot with my bf the past month. He doesn't know about our relationship anymore but refuses, I mean REFUSES to talk about it. He says we'll talk later. Well its breaking my heart and I put my foot down. He can casually text me like nothing's the matter but won't discuss our obvious problem. So I sent him a message saying he shouldn't talk to me until he figures it out. That was Thursday night. Not a peep from him except he liked my Instagram pic and has looked at every one of my snap stories since then. What gives?! How long would you wait to hear from him before telling him you need to come get your stuff from his place? How can he be liking my social media but still be this confused?
