Will Sims brake up if they catch their partner cheating?
So I have not tested this yet. In past games if you came home and caught your partner in bed with the maid your sim would freak and kick them out. Dose that happen in Sims 4? I feel like it dose no...
No, not without mods that will allow for them breakup autonomously. Sims can however autonomously ask your Sim to go steady from time to time, but not to break up without mods.
