How comparing yourself to your partner’s ex can harm your relationship: Know how to stop

The term ‘Rebecca Syndrome’ comes from Daphne du Maurier’s novel Rebecca, where the protagonist is haunted by the presence of her husband’s late wife. In real life, this manifests as retroactive jealousy—obsessing over a partner’s past relationships and feeling the need to compete with or surpass their ex.

According to Sonal Khangarot, a licensed psychotherapist, key psychological factors behind this behaviour include:

• Insecurity and low self-esteem, leading to doubts about one’s worth in the relationship.
• Social media exposure, making it easier to compare oneself to an ex.
• Unresolved trauma from past relationships, making individuals more prone to jealousy and obsessive thoughts.

How does this affect your relationship?

Constantly measuring yourself against your partner’s past can erode trust and intimacy, leading to:

• Emotional distance as the individual making comparisons may feel unworthy.
• Resentment from the partner, who may feel unfairly scrutinised.
• A toxic cycle of insecurity, creating ongoing conflicts and misunderstandings.

How to break free from comparison and insecurity

Khangarot suggests practical strategies to overcome ‘Rebecca Syndrome’:

• Practice gratitude – Focus on what’s valuable in your current relationship instead of fixating on the past.
• Journal your thoughts – Writing them down helps process emotions and gain clarity.
  Limit triggers – Avoid stalking the ex on social media or revisiting old memories that fuel insecurity.
• Seek professional help – Therapy can help address underlying self-esteem issues and rebuild confidence.

Relationships thrive on trust, communication, and self-assurance. Overcoming ‘Rebecca Syndrome’ means letting go of past comparisons and embracing your own worth in the relationship. Instead of competing with history, focus on building a stronger, happier future with your partner.
