Things are really different for girls. Even the ones who seem the most confident on the outside, have their reservations and dislike things about themselves. So when they love someone, and another girl comes in between that, it's a huge threat...not only to their relationship but to their self-esteem, and they can be left wondering what it is another girl has that she doesn't. It goes much farther than a guy thinks. It can destroy even the happiest, most confident girls. It just comes down to wether or not a girl is going to let that destroy her I guess.
