Romantic interest in TS4

Thanks for the information, Sindocat. I can understand the dynamic of the "ice being broken" because my Sim flirted with someone and she was receptive. He might flirt with her occasionally to see how their chemistry developed.

My Sim isn't the kind of guy who would flirt with a woman in front of another woman he's been flirty with. Even at a party, he would keep it classy and simply be friendly. This kind of dynamic seems to be captured fairly well in TS4.
