Got ghosted?

So I got a friend request from this guy bout a month ago. We started to chat and hit it off crazy good. Like better than I’ve ever hit it off with anyone. We were attracted to each other in every way. Listened to same exact music. Had same common grounds, almost same life events, views on things etc. and it wasn’t fake it was a natural flow of easy and fun getting to know each other. He even said he wasn’t looking for anything as I wasn’t but what do you do when something happens that feels so right and on point? We established friendship but nothing more in this period but both really looking forward to more. It was expressed on both sides. Sexually charged too so that was a big plus of possibly something going down in person eventually. All the sudden he started to pull away and within couple days nothing. I haven’t messaged him much more because it was clear he wasn’t feeling it. Just a little put off by it all and puzzled. Any thoughts? Obviously I’d have to ask him to know but my pride and ego is a little bruised.
