How many marriages?

Most of my sims marry as young adults and stay together. I've had a few divorces over the sim-years I've played... but very few. I can think of four divorces. One poor sim -- who liked to hit the juice a bit -- was divorced twice. Another married a second time after her husband died, but it didn't work out. A third happened only recently, so no idea how that story will turn out. A fourth very recent divorce seems to have been the right thing for the couple. He's already remarried and is truly happy. His ex-wife has also found her true love and is hoping for a proposal very soon.
