Relationships can be built between your sim and other sims in The Sims 2. The relationship level your sim has with other sims can be improved by interacting with them or giving them gifts. Likewise, the relationship level can be decreased by squirting sims with the Super Drencher. Below is a list of the relationships in the game. When sims are "in the mood" or loopy, relationships will have different titles (e.g. best friend becoming soul mate) however, this title is reverted back when they're romanced or restrained.
- Best Friend - This is the top relationship.
- Aquaintance - This is the default relationship with all sims upon meeting them.
- Nemesis - This is the lowest relationship.
