Christians are prone to hormones and temptations same as anyone else, they just make a more conscious decision not to follow through on those types of feelings.
It sounds like the gentleman in question does have feelings, certainly curiosity about you romantically (perhaps brought on by you exclaiming your own feelings) but he knows he's not in the right place to take it anywhere... At least right now.
I would stop thinking about him, and make a more conscious effort yourself to avoid paying undue attention to him.
For instance, for you to even notice that he's noticing you means your doing your fair share of staring at him/stealing glances, though you may not consciously recognise your doing it yourself.
What your doing, however unconsciously, is clearly bringing attention to yourself. So make a more conscious effort to avoid paying him any attention and live your life.
If it's ever the right time for both of you at the same time he'll make it known, but I wouldn't even consider that potential. I'd just move on - meaning stop noticing what he's doing, and stop caring about what he's doing.
