The one thing the Sims 4 does better than the other Sims game I've played is kind of wack -- abusive relationships. Getting the friendship bar down while keeping the romance bar up leads to some seriously messed up scenarios. Hurl insults and then make up in bed. In Sims 3, since the friendship/romance bar are the same, being mean just drops the overall relationship, and if it gets too low, they break up. I think it's pretty weird given that the "point" interaction was taken out because the person being pointed at would flinch back, and that was seen as abuse, and slap was moved to mischievous for the same reason, yet you can have an outright abusive relationship that plays so naturally I found it quite surprising.
