The short answer is yes, but it’s important to understand that narcissistic personality disorder (NPD) is a complex mental health condition that can be difficult to treat. People with NPD tend to have a deeply ingrained sense of grandiosity and entitlement, and may struggle to empathize with others or take responsibility for their actions. That being said, if a person with narcissistic tendencies is motivated to change and willing to participate in therapy, couples therapy can provide a supportive environment for them to work on their behaviour and communication patterns within the context of their relationship. In some cases, couples therapy can also help the non-narcissistic partner learn strategies for managing their own reactions and setting boundaries. If you do decide to pursue therapy with a narcissistic partner, it’s important to find a therapist who has experience working with narcissistic personality disorder, and to have realistic expectations for what can be achieved in therapy.
