Search Results: should i approach him

I met this guy 3 weeks ago at a concert. I went by myself. His friends approached me and we ended up hanging out for the night. He flirted but never made a move. His one friend was drunk and got my number before I left for the night. Next day, his friend asked me out, I politely declined, explaining I had chickened out from asking the guy I was interested in for his number. The friend said the guy heard me telling another guy I had a boyfriend (I don’t, I do this when I’m out alone to easily reject guys). The friend also sent me the guys number and said he thought I should text him. I did. We texted everyday for a week and he called me 3 or 4 times to chat. First time he called he said he was not a good texter and preferred calling (if I was good with that). Throughout the week we got to know each other a bit. He made sure I knew he lives a few hours away (he is moving soon tho), and that he is 9 years older than me. The last call we had was ~ half an hour and went really well. He teased me and called me nicknames, said his friends thought I was really cool, and mentioned different things we could do together. He told me he was going on a trip that weekend and at a music festival the following weekend so he would be super busy. He told me he was just a call away before we hung up.
I texted him the next morning responding to something he sent the night before. I asked a question about something we discussed on the call and he never responded to the text. A week after our last call, I had not heard from him so I texted again. I said I might be able to make time if he wanted call me again sometime that week. I figured I was likely getting ghosted, so I mentioned if he wasn’t feeling it that I understood and it would be no hard feelings. He texted back a couple days later adamantly saying he definitely wanted to keep talking. He never called though, and that was about 5 days ago now. Should I consider myself ghosted? If not, is it likely he’s just not very interested?
