Relationship Maintenance and Dissolution
Relationships don't just happen and then stay on autopilot. They require ongoing effort to maintain, and they can face challenges that lead to their end. This section covers the strategies couples use to keep relationships strong and the factors that contribute to breakups.
Understanding these dynamics matters because they reveal why some relationships last while others don't, even when initial attraction was equally strong. The theories here connect satisfaction, commitment, and investment in ways that explain a lot of real-world relationship behavior.
Relationship Models and Theories
Commitment and Investment Models
The commitment model explains relationship stability through two forces: dedication and constraints. Dedication is your personal desire to stay in the relationship because you want to. Constraints are external factors that make leaving difficult, like shared finances, children, or a joint lease.
The investment model (developed by Caryl Rusbult) builds on this by adding a third factor: investment size. Investment size refers to the resources you've put into the relationship that you'd lose if it ended. These can be:
- Direct investments: time, emotional energy, self-disclosure
- Indirect investments: mutual friends, shared possessions, a life built together
The model predicts commitment based on three variables:
- Rewards: positive aspects like companionship, emotional support, fun
- Costs: negative aspects like arguments, sacrifices, stress
- Investments: resources already sunk into the relationship
The key prediction: high rewards, low costs, and large investments produce the strongest commitment. This explains why someone might stay in a mediocre relationship if they've invested heavily in it. Walking away means losing everything they've put in.
Interdependence Theory
Interdependence theory focuses on how partners influence each other's outcomes and how that mutual influence shapes the relationship. Two concepts are central here:
- Comparison Level (CL): the standard of outcomes you expect from a relationship, based on your past experiences and observations. If your current relationship exceeds your CL, you feel satisfied. If it falls below, you feel dissatisfied.
- Comparison Level for Alternatives (CLalt): the perceived quality of your best available alternative to the current relationship. This could be another potential partner, being single, or investing more in friendships and career.
Satisfaction depends on how your current outcomes stack up against your CL. Dependence depends on how your current outcomes compare to your CLalt.
This distinction is important: you can be dissatisfied but still dependent on the relationship if your alternatives are worse. That's how the theory explains why some people stay in unhappy relationships. It's not necessarily that they're content; it's that they don't see a better option. The theory also emphasizes that both partners' perspectives matter, since each person has their own CL and CLalt.

Relationship Maintenance Strategies
Accommodation Processes
When your partner does something negative (snaps at you, forgets something important, acts selfishly), how you respond matters enormously for the relationship's future. Accommodation means responding constructively rather than retaliating.
Rusbult's accommodation model identifies four response types, organized along two dimensions (active vs. passive, constructive vs. destructive):
| Constructive | Destructive | |
|---|---|---|
| Active | Voice: discussing the problem, suggesting solutions, seeking compromise | Exit: threatening to leave, actively damaging the relationship |
| Passive | Loyalty: quietly supporting the partner, giving them the benefit of the doubt, waiting for things to improve | Neglect: ignoring the partner, withdrawing emotionally, letting things deteriorate |
Voice and loyalty help maintain relationships. Exit and neglect erode them. What determines which response someone chooses? Two major factors:
- Commitment level: Highly committed partners are more likely to bite their tongue and choose voice or loyalty over exit or neglect.
- Attachment style: Securely attached individuals tend toward constructive responses, while insecurely attached individuals are more prone to destructive ones.
Forgiveness and Social Support
Forgiveness involves letting go of negative emotions and resentment toward a partner who has caused harm. It's not about excusing the behavior; it's about reducing your negative responses (anger, desire for revenge) and gradually increasing positive ones (empathy, goodwill).
Several factors influence whether forgiveness happens:
- Severity of the transgression: minor offenses are easier to forgive than major betrayals
- Relationship satisfaction: people in happier relationships forgive more readily
- Empathy: the ability to understand the partner's perspective facilitates forgiveness
Forgiveness benefits both the relationship (improved quality, restored trust) and the individual (reduced stress, better well-being).
Social support is the other major maintenance tool. It comes in three forms:
- Emotional support: empathy, comfort, reassurance
- Instrumental support: practical help like running errands or sharing tasks
- Informational support: advice, guidance, useful perspective
One research finding worth knowing: support can be visible (direct, obvious offers of help) or invisible (subtle, behind-the-scenes assistance the recipient may not even notice). Invisible support is often more effective because it doesn't threaten the recipient's sense of competence or self-efficacy. Nobody likes feeling like they can't handle things on their own.
For support to work well, the type of support needs to match what the person actually needs. Offering advice when someone just wants comfort can backfire. Reciprocity also matters: relationships where support flows in both directions tend to be more satisfying and stable.

Relationship Outcomes
Relationship Satisfaction and Alternatives
Relationship satisfaction measures how content and fulfilled someone feels in their partnership. The main drivers include communication quality, shared activities, and emotional intimacy. Satisfaction tends to fluctuate over time as life events (a new job, having kids, financial stress) shift the balance of rewards and costs.
High satisfaction is linked to greater commitment and longer-lasting relationships, but satisfaction alone doesn't determine whether someone stays. Perceived alternatives play a critical role:
- Low-quality alternatives (no appealing partners available, fear of being alone) tend to increase commitment, even in less satisfying relationships.
- High-quality alternatives (an attractive coworker, a thriving social life as a single person) can decrease commitment, especially when satisfaction is already low.
Perception of alternatives isn't purely objective. Factors like self-esteem and the size of someone's social network shape how many options a person believes they have. Someone with high self-esteem may perceive more alternatives, while someone with a smaller social circle may perceive fewer.
Relationship Dissolution
Relationship dissolution is the process of ending a romantic partnership. Duck's model describes four stages:
- Intrapsychic phase: One partner privately mulls over dissatisfaction and doubts. They weigh the relationship's pros and cons internally without telling their partner.
- Dyadic phase: The dissatisfied partner raises concerns with their partner. The couple discusses problems and may attempt to repair the relationship.
- Social phase: The breakup becomes public. Friends and family get involved, sides may be taken, and the couple negotiates the social fallout.
- Grave-dressing phase: After the breakup, each person constructs their own narrative of what happened and why. This is the "making sense of it" stage.
Common factors that contribute to dissolution include lack of commitment, infidelity, and communication breakdown. The consequences vary widely. Emotional distress is common, but so is personal growth. How well someone adjusts after a breakup depends on factors like whether they initiated the split (initiators generally adjust faster) and how long the relationship lasted.
Coping strategies that help include seeking social support, engaging in self-reflection, and redirecting energy toward personal goals. Some former couples transition into friendships, while others cut contact entirely. Both paths can be healthy depending on the circumstances.
