Do you really need an answer to that question? Yes you should be ashamed that you’re attracted to your step-son. Hopefully your step-son is an adult? If not then you are crossing the line in more ways than one; but for the sake of this post we’ll assume that you’re referring to a step-son who is adult. Even if we were talking about your husband’s brother or his friend it would be inappropriate for you to harbor an attraction to them, so imagine how much more inappropriate it must then be to harbor an attraction for your husband’s son. Pull yourself together and spend that energy on your husband and your marriage.
