Also, you have to use the friendly interaction a few times, I think on mine, it was like 4 or 5 times, before "move in" came up. What I was doing was switching back and forth between romantic and friendly and it would not give me "move in", until I quit using romantic and just kept using friendly and of course I read that here. It doesn't take long, but like Pam said, it is easy to change their name at city hall, but for some reason, the meaning is not the same, but my own trait is hopeless romantic, so I always want the guy to do the asking and have some romance in the mix. lol
Go figure.
