LOL, this guy would be laughing his ass off if he knew how bad he got you. Upset enough to post on a forum about him, no less.
He's a jerk. A turd. Do you agonize about your dumps every time you flush? This isn't about you at all. You are fine.
BTW, you might want to google 'PUA technique' and get educated. Insulting you and then making a move on you is a standard technique for players. Its actually attractive to a subset of insecure females. What you did was prove you weren't one of them, so he immediately lost interest (getting offended is the last-ditch attempt to draw you in--some useless women will actually apologize and let the guy **** them).
Laugh this chode off and spend your energy looking out for a nice young man. They are out there.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
