Dear SABI9JA: Will My Sister Develop Emotions For My Husband If I Allow Her To Work As His PA?

From a female  reader

My husband is suggesting that my young sister become his Personal Assistant as she has been out of school now without a job but am skeptical about that knowing that the job would afford her to be too attached to my husband which can result to emotions building up. Is my reservation in order or should I just allow it?
