yeah
even though you did not "say no completely" you still "turned him down"..
which that can hurt an ego...
i'm sure he thought he was doing everything right with compliments and
flirting... adn then when you turned him down he second guessed himself
because you made it look like it wasn't working..
idk that's just what i see..
maybe try to explain to him why you think you guys should get to know
each other better....
