oh, you consider having your romance sims have children is ruining thier lives? shoot, I do that all the time. lol. I mean, I'd think if you slept with most of the town eventually you're going to have a kid or two. lol.
I only killed some townies on purpose once. lol. I had a romance sim in college that decided to change to a Popularity sim when I had the opportunity to change it (this was before I had InSim). She had a lot of lovers in the game due to her romantic past, but after she graduated and I wanted her to settle down with one sim she kept getting wants to meet with the others all the time.
so what I did was buy a cowplant and place in in front of her house. I would invite the college guy over and he'd try to grab the cake and he'd be gone. no more getting annoying wants to call and invite them over. Bwahahha
