“him” is a bit too vague here. If you were to try to answer this with text input, you’d immediately think to use 彼, but the answer is 旦那, which has numerous meanings depending on context. In this context, I am assuming it is husband, due to the personal nature of the sentence. It is also the only modern usage of this word that I am personally aware of. I have heard people say 旦那 or 旦那さん.
