Ick is gooooooooood :) It tells you not to waste someone else's time too :) No one is going to be perfect post marriage either, You may have a bad day, a genuine temper outburst at someone, may speak in the movies, may take an interest in star signs. If these are reasons to avoid an otherwise wonderful connection, one might as well choose to not enter the dating sphere. I know there can be genuine red flags, but this ick thing is just nit picking.
