An attractive women needs to offer more than just her looks to be with you.
If she knows her looks is all you want, she will conclude you are just using her and only want to sleep with her.
If she has to work and pay attention to you, in order for you to be attracted to her, she will feel better about herself and feel you are more of a high-valued, selective, alpha male.
That is, for her to like you, she must treat you well. Do not settle for anything less.
