i hope you do get together with this person, if its meant to be you will somehow get to know him better and i would wait for a positive moment to ask him for coffee. maybe you don't want to but you could flirt some more and see how he reacts, if he's not interested he should tell you, if he is decent. i know when i wasn't married i loved to flirt. it was fun. maybe he is just flirting but he may like you alot too. good luck
