I think many people, men and women, get addicted to the anxiety and fear they feel when they are attracted to someone that treats them badly. They feel like these feelings are love or longing and that it means they have stronger emotions for these people who aren't as nice. The nice people seem "boring" or "weird" because of the lack of the negative feelings that they associate with being "in love." The insecurity seems to make them feel like that other person is "worth fighting for," but in reality, its just insecurity driving them nuts.
