Successful stories are driven by authentic and interesting characters, so it’s important to craft them carefully. But characters don’t usually exist in a vacuum; throughout the course of your story, they’ll live, work, play, and fight with other cast members. Some of those relationships are positive and supportive, pushing the protagonist to positive growth and helping them achieve their goals. Other relationships do exactly the opposite, derailing your character’s confidence and self-worth or they cause friction and conflict that leads to fallout and disruption. Many relationships hover somewhere in the middle. A balanced story will require a mix of these dynamics.
The purpose of this thesaurus is to encourage you to explore the kinds of relationships that might be good for your story and figure out what each might look like. Think about what a character needs (good and bad), and build a network of connections for him or her that will challenge them, showcase their innermost qualities, and bind readers to their relationship trials and triumphs.

Description: There are very few people in this world who don’t have a romantic ex or two (or five?). When it comes to our characters, certain factors will impact the dynamics of this relationship and should be considered. Is the ex a spouse, lover, or boyfriend/girlfriend? How long did the relationship last? Are there shared responsibilities that keep the ex involved in the protagonist’s life? Has the ex moved on, bringing new personalities into the mix that could create issues for the character? Was there abuse, infidelity, or another damaging event that would cause more than the usual bad feelings? Whatever the factors, this relationship will bring with it emotional baggage and inherent conflict, making it a good one for our fictional characters.
Relationship Dynamics:
Below are a wide range of dynamics that may accompany this relationship. Use the ideas that suit your story and work best for your characters to bring about and/or resolve the necessary conflict.
Remaining friends after the breakup
Spending holidays or vacations together to maintain stability for the children
Continuing to cohabitate after the breakup (to save money, until a new job or apartment can be found, etc.)
Maintaining a civil relationship because of a shared goal (raising a child, owning a business together, etc.)
Agreeing to make certain important decisions together, such as when a child should get a phone or start dating
Putting on a happy face and hiding the negative emotions that crop up when the ex is present
Ignoring each other when the two people come in contact
Being dependent on the ex (pining after them, responding to every overture of reconciliation, continuing to seek them out for help, becoming obsessed, etc.)
Refusing to be in the same room together
An inability to be together without fighting
Forcing friends and family to choose sides and cut ties with the ex
Using people and circumstances to punish the ex (by seeking custody of the children, withholding alimony payments, etc.)
Running down the ex to friends or children
Actively sabotaging the ex
Conflicting Desires that Can Impair the Relationship

Bitterness, anger, and an inability to forgive making it hard for the character to move on
Reluctance to move into new romantic relationships
Losing the moral high ground—e.g., the breakup may not have been the character’s fault, but the way they respond in the aftermath drops them to the ex’s level
Losing family and friends over the breakup
Children seeing the way their parents fight and modeling those behaviors
Losing something else that’s important (a pet, custody of the children, one’s home, etc.) because the character couldn’t behave civilly
Fictional Scenarios That Could Turn These Characters into Allies
A child’s rebellion or unhealthy coping practices (drug abuse, unsafe sexual practices, self-harming, toxic relationships, etc.) requiring an intervention or rescue
Recognizing that a truce must be negotiated for the sake of the children
A financial difficulty that would be solved by them continuing to live together
A business opportunity that is perfect for both of them as a team
