First of all, this should have been posted in the Console section. That said, let's get to your problem. Did you check if the option was available in the Friendly menu, and in the Romantic menu? Do you, in X360, have to create a momentum to make new interactions available, like in the PC? If none of these solve it for you, perhaps you could try using the phone and moving your sim over to the husband's house, and then move both of them back to your place (if that's possible in X360)?
