Got ghosted and I simply don’t get it

It’s like the classic story of girl gets ghosted. I didn’t even want to date this guy. I convinced myself nah he’s not for me and then for some odd reason I said fine I’ll go on this date. We had three great dates. We spoke everyday for a month and a bit. And the last date he said let’s meet tomorrow. Now nothing. Absolutely nothing. I’m so confused with all the relationship ship type intimacy. How do u get over this I don’t understand. I’m not gonna text and be like explain the reason! But I’m so lost.
