Hi CLwife,
I am not a therapist but it seems more an obsession than a simple infatuation. To me the most important elements are not in the characteristics of this Korean celebrity but in all what your infatuation is hidding. Perhaps you can see this as a path of discovery of yourself. I think you have asked for help here because a part of you knows that this is not only about her, but it is mostly about you. Please, don't be afraid of going to a professional and tell her/him about your feelings. Professionals are trained to hear all kind of things. Please, keep posting
Sending you a hug
