For the most part my sims are single and loving it, which I found out is a tough lifestyle to break. The ones who are settled down are not interesting any more. Can't describe it, just stop finding them interesting...always babies and kids to take care of, eww. :D I love the toddlers but boy can it ever wreck a sim's style.
My single sims live life fully, they travel, have relationships all over the world. When they do want to settle down, they tell former lovers they just want to be friends. So far I've had 2 couples divorce and it's tough, even for sims.
