Invited Sim over, Says "On my way", Immediately cancels visit.

I posted about this issue before, and the response I got was to purchase the Legendary Host moodlet thing, then throw a party with the Sim invited. I did it on three separate occasions, and it didn't work. I've also used resetSim. I didn't work. The Sim was very pregnant when she was invited over. I've read in a couple different forums that that could be a reason for this happening. However, they never gave a way to fix it. ):

I'm sorry the invite to party doesn't work, maybe because she is very pregnant.  Have you tried going to her instead?  Have your sim go to university again, and try to find her in the university town where you met her?  Or you could let her deliver the baby, then try to invite her over for party.

Thank you for the help. I tried, and it didn't work. It's almost like the Sim disappeared. She isn't in University anymore, and she doesn't have a home in my regular town. If I ask her out on a date, she never shows up saying "Something came up" again. It's been at least two weeks (Sims time). She's had plenty of time to pop that kid out! On that note, I've also been checking my family tree to see if she and the baby have been added. They haven't been. It's still just myself and ex-girlfriend.

There is a cheat to add sim to household, however you still need to find the sim and click on the sim.  Don't think there is anything else left you can do except to forget about that sim and move on.
