I don't know what your company policy is about co- workers fraternizing, but it's possible the bantering flirtation you have developed fed a rumor machine that embarrassed him.
In fact, I'd bet that rumors are flying around about you!
You haven't said if he's single or not, or if you are, for that matter...but it's likely he's been told that the flirtation at work is inappropriate. so now he avoids you and acts nervous., He won't tell you directly not to flirt with him, since he certainly does like you, but he feels he has to keep his distance and maintain 'professional' decorum from now on.
Naturally, the whole situation makes him nervous, since of course he'd like to keep flirting, but feels he has to stop.
That's happened to me, several times, in work situations..I know how he feels!
