The law of attraction?

Does the law of attraction works here?  Like attracts like, hate attracts hate?  How can this be true?

How can I, a loving and caring daughter, a kind and loving lover and wife to my husband, be attracting such a mother in law?  Is this the only time the law of attraction does not work?  Is this right?  I have always ask myself these questions since the day of the appearance of my mother in law.
