This blog is a very original way to adress a problem. I had this problem in my game, except when I didn't have any expansion packs installed. Sunset Valley was actually a very lively city where people would get married and have many kids, but due to glitches, many kids would die young, though. With expansion packs, especially Generations which introduces reputation, it's much easier for Sims to catch Sims cheating, for example; even the ones you're not playing with. This often causes Sim to break up autonomously, which didn't happen in my previous game archives. Even if a Sim caught the spouse cheating on them, the two would lower their relationship and trust on each other, but they would stay together. That doesn't happen anymore. I've found many young couples breaking up for this reason. And I don't know, but I think this is just one of the factors. I also realize most pre-made single Sims never marry, they just get romantically interested in someone and sometimes have a child, but nothing very serious.
