Separating/ Divorcing your Sims - TS4

I cause break ups if I get bored enough, but I also let them work out their issues sometimes, even if they do it in separate households for a while. The break ups don't always involve cheating either, sometimes I have them argue over one working too much and not helping around the house, someone getting too caught up in their career and not helping with the kids, etc... It just depends on the story I'm trying to tell. Divorces were more fun in the TS2 days, although I did like that TS3 gave us self-help books.
