i like how u express urself, with the text.....my eyes blur
liao...... 
dont take things too hard loh...its all 'mind over matter' - if u
dont mind, it doesnt matter.
look on the brighter side, if u feel no chemistry with him, than
let him go fock himself....
but if u do haf chemistry with him, but he is proven to be such a
flirt, and u wanted to be with him ALOT, than prepare to change him
loh...of course, u will get hurt in the processs.
i recommend u to find some one else gd enough for u...failed
relationship, let it served as a form of lesson...come to think of
it, u dont need to pay $$ also leh....but dont give ur body away
too easily loh.
