I have a MAJOR family issue! please help?

Wow. First, just make a really hot guy come in and have him start making out with Kaylie. Then let Lindsey see this. She'll be sad, thus she won't like Kaylie anymore.You'll come in and comfort her. She'll love you again. As for Bailey, yell at her. Make her mad. She'll get really pissed. Then apologize. She won't be as clingy from now on, but she'll still love you. BOOM! Everything is back to normal. And nobody has to move out. :)
