This is truly remarkable. I am in almost the same situation at work (I'm a dummy), yet on the totally opposite side. I'm the older guy who the younger woman said no to since, in her mind, our age gap was way too much to overcome. You've gotten tons of good perspective here. Speaking as the guy who got completely turned down, I can tell you I would not keep you close unless there was something I wanted. There is obvious intrigue on his part, but once I get turned down more than one time, I will absolutely stop trying. Life is too short to chase those who don't want you. As others stated, just keep that professional attitude and always stay cool, calm, and collected when you end up bumping into him. You seem to have done well since your original post. That's good to see.

I know it is easier said than done, but for both your sake, I would keep the communication with him to a minimum.

It would take a lot of time and energy to clear the air between the two of you.

Just keep things professional and leave it be.
