Loving a Narcissist: How Narcissistic Personality Disorder impacts Love and Relationships

The term "narcissism" is everywhere these days—used to describe everything from overconfidence to outright selfishness. But what does it really mean? How does narcissism impact relationships, and why is it so hard to navigate? These are some of the big questions Jacqueline Trumbull and Dr. Kibby McMahon tackled in an episode of their podcast “A Little Help For Our Friends”, featuring guest Dr. Diana Diamond, an expert clinician, professor and researcher of narcissistic disorders.

As a listener, I was struck by the depth and relatability of the conversation, which bridged clinical knowledge with the lived experiences of those entangled in relationships with narcissists. Here's a recap of the episode’s key insights:

What is Narcissism, Really?

Dr. Diana Diamond began by unpacking the term "narcissism," which, she explained, exists on a spectrum. At its healthy end, narcissism fosters self-confidence, ambition, and the drive to achieve. At its extreme, it becomes pathological—marked by a rigid need for admiration, a lack of empathy, and an exploitative approach to relationships.

Dr. Diamond broke narcissism into two distinct forms:

  • Grandiose narcissism: Defined by arrogance, entitlement, and overt displays of superiority.

  • Vulnerable narcissism: Less visible but equally damaging, this type is rooted in insecurity, hypersensitivity to criticism, and covert grandiosity.

These clinical distinctions shed light on why narcissism can appear so differently from one individual to another, yet still leave a trail of emotional turmoil.

The Narcissist in Love

Jacqueline and Dr. Kibby’s discussion hit home when they explored how narcissism manifests in romantic relationships. Relationships with narcissists often begin with a whirlwind of charm and passion, thanks to the "idealization" phase. This is when the narcissist places their partner on a pedestal, showering them with admiration and affection.

But as Dr. Diamond pointed out, this phase is short-lived. Once the partner inevitably falls short of the narcissist’s unrealistic expectations, the relationship shifts into "devaluation." The very qualities that were once celebrated are now criticized, creating a disorienting cycle of emotional highs and lows.

For listeners who’ve experienced this dynamic, it’s a powerful realization: the rollercoaster isn’t about their own flaws but the narcissist’s inner turmoil.

Understanding the Narcissist’s Inner World

One of the most illuminating parts of the episode was Dr. Diamond’s description of the narcissist’s inner world. Beneath the bravado lies a fragile self-esteem, often shaped by early childhood experiences of neglect, criticism, or unmet emotional needs.

To protect themselves from these vulnerabilities, narcissists construct a grandiose facade—projecting an image of perfection to themselves and others. This defense mechanism keeps shame and insecurity at bay, but it also makes genuine intimacy and self-reflection incredibly difficult.

Jacqueline and Kibby approached this topic with compassion, acknowledging the pain at the root of narcissistic behavior while remaining clear about its destructive impact on relationships.

The Partner’s Perspective

The podcast also gave voice to those who find themselves in relationships with narcissists. Jacqueline and Kibby highlighted common experiences, such as:

  • Gaslighting: Narcissists often distort reality, leaving their partners doubting their own perceptions.

  • Emotional exhaustion: Partners can feel drained from constantly propping up the narcissist’s self-esteem while neglecting their own needs.

  • Confusion: The stark contrast between the idealization and devaluation phases leaves many partners wondering what went wrong.

As Dr. Diamond emphasized, these behaviors are not reflections of the partner’s worth but symptoms of the narcissist’s internal struggles.

Can a Narcissist Change?

For many listeners, the burning question was whether narcissists can change. Dr. Diamond offered a nuanced answer: yes, but it’s a difficult and long-term process. Effective therapies, like transference-focused psychotherapy, can help narcissists confront their vulnerabilities and develop healthier relationship patterns. However, the key is willingness—something many narcissists lack, as their defenses are deeply entrenched.

For partners, Jacqueline and Kibby stressed the importance of setting clear boundaries. While it’s possible to stay in a relationship with a narcissist who is actively working on themselves, self-care and emotional safety should always come first.

Final Thoughts

As the episode wrapped up, I found myself reflecting on how profoundly narcissism affects not only those who have it but also the people who love them. Jacqueline, Kibby, and Dr. Diamond didn’t shy away from the pain narcissistic behavior can cause, but they also brought empathy and understanding to the conversation.

For anyone who’s ever been caught in the web of a narcissistic relationship—or simply wants to understand this complex personality trait—this podcast episode is a must-listen. By blending expert insights with relatable storytelling, Jacqueline and Kibby made an intimidating subject approachable, enlightening, and even hopeful.

If this topic resonates with you, I highly recommend tuning in. The clarity and compassion they brought to this discussion are a reminder that, even in the most challenging relationships, healing and growth are possible.
