I admit, I usually make my Sims' lives pretty boring. They're always kind of perfect. So I decided to spice things up and add a little drama. For no reason at all, I had the husband cheat on the wife ...
Its a lot of fun, IMO, trying to get them to reconcile because the relationship is harder after they cheat. I do wish that they would bring back alimony and child support from TS2 and the self-help books from TS3. If they'd bring back the awareness of cheating from TS3, that would be the icing on the cake. I miss other sims being able to expose a cheating sim.
