Why has he stopped liking my pictures?

Okay me and this guy have been chatting and we plan on hooking up ( I live in another state lol so I'm flying there with my friend for a trip and he is there so) well we talked and I purchased his artwork ( he's an artist) and we actually had a conversation without talking about sex. However, he has literally stopped liking my Instagram photos and has stopped viewing my Snapchat stories and I don't know wtf I did lmfao! He texted me yesterday asking for my shipping address to ship the painting. And I gave it to him and that was it. Why would a guy stop doing this when I literally supported him? is he being rude af?
