It seems like my relationships on the romance level die very quickly and almost, goes the opposite unless constantly talk to each other. I've tried repairing the game but still seems to be an issue
Ideas
Do you have lovestruck? It's like that since Lovestruck. The only way ive been keeping my sims romance bar high/full is by having them woohoo everyday (my sims live together). My other save the partners of my sims that arent living in the household lose at least half of the bar within a day.
