Janie, I put my own remarks about men making bad choices too in parentheses because the thread title specifically concentrates on 'girls'.
I remember when I was young (hundreds of years ago!) viewing 'bad' men as rather romantic. They had adventures, went a bit wild and fought boldly with other chaps, being fearless and brave. They seemed more sexy than a man who would listen, help do the dishes and never take risks. And I found 'needy' down-on-their-luck poor men pitiable; they awakened in me a desire to help them. (Typical rescuer). I can really relate to young women who feel the same attractions. The whole idea shifts drastically when one considers the same men as potential husbands and fathers. Where children are concerned, losers and baddies are no good at all.
