Great hookup on a NYC visit, then silence — because of distance or disinterest?

Matched on Hinge and hit it off right away - great banter. Met the next day and had chemistry and long personal conversations. Hooked up at his place afterwards - twice. He wasn’t pulling back then. I texted him the next day and he replied warmly, but stopped once I implied I’d be open to meeting again. I live in Europe, he lives in NYC and I was leaving in two days. It was meant to be a one-off, but because there was a connection and I had fun I wanted to repeat before I left. Did he ghost because we live on different continents and due to him being practical or because it just wasn’t great for him?

I‘ll be there quite often in the future. Should I tell him that or just leave it?
