Long distance struggles

I've known this guy for a while and we've tried to talk for a few months now but he keeps ghosting me. We've recently been talking again and it's been better then ever before. (we only have each other on Snapchat) He hasn't been opening my messages or pictures. However he will look at my stories. What do you think he's doing? Is he trying to ghost me again? He said that he's been busy at work but he hasn't been giving me an explanation as to why he won't answer me. I'm too scared to bring it up because he is the first guy I've ever had true feelings for, not just a high school crush or whatever. I saw this thing called "The boyfriend cleanse", should I try that? What should I do? I need help!
