I sent nudes to him but now he is ignoring me and left me on opened. why?

Basically me and this guy have been flirting for a couple of months. I liked him but I wasn't sure if he liked me. Last month he kept asking for nudes. And finally I gave in. we shared nudes about twice. suddenly like 3 days after the second time he started snapping less. Finally he left me on opened. I was pissed so I sent him a chat, but then deleted it. he replied saying "no" and I left him on opened. I don't know what he is thinking.
