Self-esteem plays a major role in relationship choices. Individuals who struggle with self-worth may accept less than they deserve. They might believe that being chosen—at least partially—is better than being alone. Over time, they may rationalize the situation, convincing themselves that the relationship will eventually become something more stable or legitimate.

Misleading Narratives

In many cases, the married partner may frame their situation in a way that reduces guilt. They might claim their marriage is “basically over,” that they are staying only for children, or that they are emotionally disconnected from their spouse. These narratives can create hope and justify continuing the relationship. The person on the outside may begin to believe they are not interfering, but rather helping someone who is already unhappy.

The Thrill of Intensity

Relationships that are hidden or complicated often carry a heightened sense of intensity. Secrecy, limited time together, and emotional highs and lows can create a powerful, almost addictive dynamic. For some, this intensity feels more exciting than a stable, predictable relationship. However, what feels passionate in the moment is often rooted in instability.

Avoidance of Commitment

Interestingly, being involved with someone who is already married can also serve as a way to avoid true commitment. Since the relationship has built-in limitations, it prevents deeper responsibility or long-term planning. For individuals who fear vulnerability or commitment, this kind of situation can feel safer—despite its complications.
