Well, if you have InSIM, you could try having her boyfriend use the Summoner to summon her. After that, you could make her selectable in one of two ways that I know of A) Using boolprop testingcheatsenabled true and then clicking on,
I think, the mailbox or B) Use the
Teleporter Shrub. If she exists at all, you should be able to summon her and then have her move in.
