The Sims 3 Kinky World

[michaellsmith60]

I ran into something I might have caused by my in-game actions. I killed a wife with poison, I guess I had it because I'm an assassin, and get the character hitched to the one who was trying to get the first wife to fall in love with her. That's been interesting, but then I get a big message with a checkmark and an X that said, "Three's a crowd in romance. You might have to dial it down a bit. Do you want to do this?" I checked it and immediately both characters get incessant calls asking for dates. It's a real pain and I would rather keep these two together for a while, so I exited the game without saving. I think I know what it means, but I'm not for sure, and if anyone can help, please tell me what I did wrong and what it means.
