Why do we go for the ones that arent "perfect"

Im finding myself liking this girl that I know, I know that she has a boyf and I know for a fact I shouldnt like her because of this very fact, however the point im getting at is that: She is kinda stuck up She is rude sometimes She can come across as only caring for herself I can see her clashing with other members of my family (in a perfect world if we were to go out obviously) She flirts with me and other guys (which obviously isnt good if she has a boyf) yet there are times that She is ridiculously adorable and cute She is funny She is a tease She is a playful character Yet I can see myself liking her, over looking all the negative traits that she has, one being a major factor, in that she still flirts (while not acting on it, a guy tried to kiss her and she pulled away) with other guys whilst in a relationship. I over-look these for her positive traits. Why do we always go for those that will ultimately hurt us, no matter how much we try to convince ourselves that its not worth it, yet we try anyway and get hurt?
