Dating question: What to do?

(I can’t believe I’m asking a “Does he like me? question.) Met a nice, interesting guy on OKCupid; he’s probably not a long term partner prospect. We wrote back and forth for a few weeks, then he asked to meet me. Had a nice walk and talk over coffee but no fireworks. Hugged when he left. Since then we’ve written less frequently and his notes have been pretty cursory. I liked him and would like to see where it goes, but am not overly invested. Wondering whether to just stop writing or to sort of say what I’ve said here and ask if he is still interested or not. We’ve both come out of recent relationships and have said we’re not looking for a heavy/heavy.

Please be gentle with me, I’m new to all this shit and a penguin.
