Questions: Dating

I went on a date late August with a guy from a different country.
We really liked each other and I could tell he was into me, but distance put a strain on that.
I got a little too serious about everything once I returned home, and dismissed his suggestion to send anything exposing.
We haven't really called quits, but I can tell he has pulled back and isn't going to reach out anytime soon.
I, on the other hand, still want to have a little fun and since I like teasing a little, I want to send him something suggestive (with his consent obviously).
Is that something you/men would still be open to, even if they are closing the door on serious contact?
How would you react if someone you dated, and had sex with, would suggest sending nudes after a few weeks of barely having contact and you pulling back?
