I’ve looked everywhere and can’t find an answer. I’m on generation 1 and had a second sim, from the beginning when they ask you to make a roommate. My sim has now found love and wants her wife to movie in with her, but I’m not spending 175 cash to get a new cash and I honestly just want the roommate to delete or move out.
You will have to retire the roommate and then you could try moving your new wife in. I tried to let my friend move in and it seemed to work. So try it!
