Physical attractions then

So then you see him and...chemistry. Instant attraction, magnetism ...so instantaneous, drawn to him, but it turns out not so good?
Give the good guys a chance, instant physical attraction is not a good indicator of his true qualities, give it time and allow him to prove to you that he can make you happier ?? because yoiu are already happy, right?
Just wondering if I'm making sense here...
Certainly believe that the way to go would be to give opportunity to men based on their authenticity, true values, morals and better qualities rather than just great physical attraction...
He could be like a fungus ???? and grow on you...give it a chance eh?
