Narcissistic abuse leaves scars that often run deeper than we initially realise. We hear a lot about gaslighting, and rightly so, but there’s another, equally insidious tactic that deserves our attention: triangulation. If gaslighting distorts your reality, triangulation brings in another person to further destabilise you and maintain the abuser’s control. It’s a sophisticated form of manipulation, and understanding it is crucial for healing.
What Exactly Is This ‘Triangulation’ You Speak Of?
At its heart, triangulation is about creating a power dynamic. It involves introducing a third party into a two-person relationship, usually to manipulate and control one or both individuals. This third party can be anyone: a family member, a friend, a colleague, or even a complete stranger. The aim isn’t to resolve conflict, but to escalate it, deflect blame, and keep you off balance.
Imagine this scenario: You raise a concern with your partner about their dismissive behaviour. Instead of addressing your feelings directly, they might say, “Your sister thinks you’re being too sensitive, too.” Suddenly, your sister, whether she actually said that or not, is brought into the equation. Your partner has now avoided taking responsibility for their actions and created a sense of doubt and unease within you. The focus has shifted from their behaviour to your perceived sensitivity.

This tactic thrives on creating division and sowing seeds of doubt. It undermines your self-esteem and makes you question your own perceptions. You might start to wonder if you are indeed being ‘too sensitive’, or ‘overreacting’, just as the narcissist wants you to believe.
Family Matters: When Triangulation Hits Home
Triangulation is particularly prevalent, and damaging, within family dynamics. A narcissistic parent might play siblings against each other, creating rivalry and resentment. They might praise one child excessively while constantly criticising another, fostering feelings of inadequacy and competition. “Why can’t you be more like your brother/sister?” is a common refrain in such households.
The effect of this is profound. It erodes trust between siblings, makes healthy relationships difficult to form later in life, and leaves lasting emotional wounds. Children who grow up in these environments often internalise the messages they receive, believing they are somehow inherently flawed or less worthy of love than their siblings.
Spotting the Signs: How to Recognise Triangulation in Action
Recognising triangulation is the first step towards protecting yourself. Here are some common signs to look out for:
- Constant comparisons: You are frequently compared to someone else, often unfavourably.
- Information is distorted or withheld: The narcissist shares information about you with others, often twisting the facts to paint you in a negative light.
- You feel like you’re constantly walking on eggshells: You’re afraid of saying or doing the wrong thing, as it might be used against you later.
- You feel isolated and confused: The triangulation creates a sense of division and makes you question your own sanity.

Breaking Free: Practical Tips for Dealing with Triangulation
While escaping triangulation can be challenging, particularly when it involves family members, there are steps you can take to protect yourself:
- Limit your engagement: If you recognise that someone is trying to involve you in a triangulation dynamic, disengage. For example, if your mother constantly compares you to your sister, you could say, “I’m not comfortable discussing my sister’s achievements/shortcomings. I’d prefer to talk about something else.” Change the subject or politely excuse yourself.
- Set clear boundaries: This is crucial. Be clear about what behaviour you will and will not tolerate. If someone shares information about you without your consent, let them know that this is unacceptable. “I understand you’re sharing this with me, but I’d prefer that you speak to me directly about any concerns you have. Please don’t discuss my personal matters with others.”
- Validate your own reality: Triangulation aims to undermine your sense of reality. Counteract this by trusting your own instincts and experiences. Keep a journal to record your thoughts and feelings, or talk to a trusted friend or therapist who can provide an objective perspective.
- Focus on your own well-being: Dealing with triangulation can be emotionally draining. Prioritise self-care activities that help you feel grounded and centred. This might include spending time in nature, practicing mindfulness, or engaging in creative pursuits.
The Path to Healing: Seeking Support and Understanding
Recovering from narcissistic abuse, including the effects of triangulation, is a process that takes time and self-compassion. Remember that you are not alone, and there is support available. Connecting with a therapist or trauma coach who understands narcissistic dynamics can be incredibly beneficial. They can help you process your experiences, develop healthy coping mechanisms, and rebuild your sense of self.
Understanding the manipulative tactics used in narcissistic abuse, like triangulation, is a vital step towards reclaiming your life. By recognising the signs, setting boundaries, and seeking support, you can break free from the cycle of abuse and create a future filled with healing and hope. It’s a tough path, but you are not alone, and brighter days are possible.
