HAH! I played it briefly about a decade ago and yes, I remember the arguments and fights when I tried to flirt a girl after already being involved with a guy
My husband just got me a copy of Sims 3 that I tried out, but I assumed it was the same. On the other hand...my sims had a cat, and that was such a time consuming relationship that I didn't even feel I had time to try to flirt with anybody else let alone date.... :|
