The jealousy system is severely lacking in TS4 compared to its predecessors. I'm sure we've all seen the videos comparing TS4 to past games. Inspired by Mokunoid's "Better Romantic Jealousy", but built from the ground up, this mod completely reworks the jealousy reaction system to provide more dramatic and personality-driven responses to a Sim's Romantic Boundaries being crossed.

I recommend using this mod with Romance Success Tweaks for the most optimal experience.

Note: The jealousy reactions for witnessing WooHoo are untouched for now as they are a whole separate system.

Core System Changes

• Logical Reaction Targeting: When a romantic interaction occurs between two Sims, romantically involved Sims in the vicinity will turn their attention to the situation and react according to their Romantic Boundaries. Reactions are tied to the exact romantic interaction the Sim witnessed, preventing Sims from reacting to another couple's flirt or confronting the wrong Sim.
• Fair Consequences: Partners/romantic interests are only labeled as cheaters if they actively accept or initiate romantic interactions. Sims are no longer blamed for rejecting unwanted advances.
• Personality-Driven Reactions: Reactions are now influenced by a Sim’s Traits, ensuring that their behavior feels consistent with their personality.
• Relationship-Based Jealousy Thresholds: Matching EA’s default, Sims can become jealous at 30 romance or within any official romantic relationship. With this mod, the threshold increases to 40 for Sims with Commitment Issues, Emotional Control, Unfaithful, or Kuttoe’s Stoic trait, while Jealous Sims, Sims with Uncontrolled Emotion, and teens can react at 20 romance or higher.
• Jealousy Cooldown: After a romantic jealousy reaction, Sims receive a two-hour cooldown before they can be triggered again.

Trait-Based Reactions

• Sims with Traits like Proper, Socially Anxious (Kuttoe) and Coward (Kuttoe) will be more likely to Walk Away when their Romantic Boundaries are crossed.
• Sims with Traits like Argumentative, Perfectionist, and Snob will be more likely to Argue with a cheater.
• Sims with Traits like Dramatic, Self-Absorbed, and High Maintenance will be more likely to Yell, drawing everyone's attention.
• Sims with Traits like Hot-Headed, Mean, and Evil will be more likely to Shove an attempted homewrecker.
• Sims with Traits like Jealous, Uncontrolled Emotions, and Paranoid will be more likely to Slap their cheating partner.
• Sims with Traits like Self-Assured, High Self-Esteem, and Carefree will be more likely to laugh off any failed attempts at another person hitting on their partner.

Immediate Cheating Repercussions

• Emotional Fallout for Cheaters: Sims caught cheating may experience temporary negative emotions such as Embarrassed, Sad, or Stressed, depending on their traits.
• Witness Reactions: Sims who witness cheating will not only lose relationship points with their partner but also with the other Sim involved in the affair.
• Friendship Impact: Friendship loss with the other Sim scales based on how close they were, ranging from -20 up to -50 for best friends.
• Consistent Sentiments: All Sims involved in these situations will now gain relevant sentiments more consistently.
• Reputation Consequences: Cheating Sims or those who flirt with someone already in a relationship may now lose reputation. Sims who respond to cheating with physical aggression risk losing a small amount of reputation as well.
• Area Reactions: Most Sims in the vicinity will react to the confrontation of a cheater.

How Romantic Jealousy Now Works

• When Sim A is approached by Sim C, Sim B (their partner) will place the blame on Sim C, the instigator, and wait to see how Sim A reacts.
• If Sim A accepts advances from Sim C, Sim B will react negatively to both parties.
• If Sim A rejects advances from Sim C, Sim B may either brush off the interaction or react negatively to Sim C, depending on their Traits.
• If Sim A initiates a romantic interaction with Sim C, Sim B will place the blame on Sim A and become angry at Sim C only if they reciprocate.

Open Love Life Compatibility

Relationships from Lumpinou’s Open Love Life are recognized by the jealousy system.

• Triad members count as partners when reacting to outside flirts.
• Triad members do not trigger jealousy against one another.
• Approved side partners are exempt from jealousy in both directions.

Jealous Trait Improvements

The Jealous trait has also been reworked to reduce false Jealous Pangs and make its relationship checks more sensible.

• Jealous Sims no longer get Jealous Pangs when their partner chats with a relative, an in-law, a child or teen, or someone of a gender the partner is not attracted to.
• In group conversations, Jealous Pangs now check every Sim your partner is talking to, rather than only the first Sim they spoke to, which could previously cause incorrect reactions.
• Jealous Pangs require a meaningful romantic connection to the Sim doing the talking. This means a partner, fiancé, spouse, or WooHoo partner. Jealous Pangs can also be triggered by a 30+ romance when that relationship is paired with a crush, Fated Mates, an enamored sentiment, or a Very Attracted relationship bit (from either Lovestruck or TURBODRIVER's mods).
• Jealous Pangs can now trigger no more than once every two hours per Sim.
• The Jealous trait's other effects, including feeling Confident near a partner, Tense while apart, and reactions to flirting and kissing, are unchanged.
