You know it's possible that it's not your husband that's scary but maybe she is scared of men. Who knows what experience she might have had before you got her. Heck, Loki is afraid of laundry baskets.
They are sensitive little dogs. Anyway, I agree that you should have your husband be extra sweet to her. Let him be the holder of all good things (food, treats, her favorite toy). She will learn he is a good thing.
