perhaps girls who have issues are attracted to you because they want someone to be nice to them but don't know how to change their problems so keep going back to them. Thats not about you. Its about them. But maybe you need to decide what you want from the relationship - what kind of person you want to be with. If after a few dates things seem to be going south, don't pursue the relationship. Recognize the un/healthy patterns if you can and don't commit right away. If guys have to prove themselves, so do the gals.
