This mechanic gives me such mixed feelings because on the one hand the relationship hit/loss of sleep is frustrating but on the other hand it's very realistic. As a student I had... encounters much like this. The relationship deterioration was much worse than portrayed in the game ;)
Is there a mod that allows the removable of forced Lot traits, maybe? Taking off the Party Place trait and adding Quiet to all the apartments would probably help, but you'd need a mod to do it, and I don't know of one that does that off the top of my head.
