The Open-Minded trait can be gained through gameplay (see Interactions) or bought with lifetime happiness points it’s available from childhood onwards, so it can keep the children of polyamorous parents from getting upset with their parents for having multiple partners.

Sims with this trait may get a happy moodlet from seeing their partners do romantic socials together.

All sims without this trait (even sims with Prefers Non-Monogamy!) will behave as usual.

The Open-Minded trait unlocks most of the social interactions in the Interactions section, and allows sims to not see non-monogamy (in their own and other sims’ relationships) as a betrayal as long as the terms of the relationship in question are being respected. After that, how A reacts to B’s romances with other sims will depend on A’s traits - if A has both the Open-Minded trait and the Prefers Non-Monogamy trait, A still won’t get jealous. If A and B are romantic interests but not in a committed Open or Closed relationship, A won’t get jealous over B until the romance has lasted at least kSeriousRomanceThreshold (default: 4) days.

The mod will automatically put sims in Closed relationships with each other when they become EA-official partners, unless they were in an Open relationship already.

If both conditions are met, A won’t mind B flirting with C – unless, again, B lets their relationship with A deteriorate.

Closed - A will get jealous if B starts a romance with C, unless A 1) has the Open-Minded trait and 2) also has a Closed relationship with C.

See the Additional Traits section for details. Depending on A’s other traits, the liking points threshold for A to feel overlooked by B is either kNeglectThreshold (default: 40) or kSpecialNeglectThreshold (default: 20).

Open - if A has the Open-Minded trait, A won’t get jealous if B starts a romance with C, although A may still be hurt if B lets their relationship deteriorate while flirting with C in front of them.

Take two sims in a relationship, A and B, and a third sim C not yet involved with either of them.
