Good-looking men sometimes will let a lady slip away, even sometimes to the arms of an average-looking or even below-average-looking man (or to a woman). This seems mainly due to personality (make her happy, make her laugh, etc) which it usually boils down to this, though I'm really looking into this for theories. For instance, are women intimidated by a strikingly-good-looking man? Do they assume that certain man is a player? By the way, I rarely see two equally good-looking partners in a couple. Any thoughts?
