Narcissists can be quite charming and seemingly faithful in the beginning of a relationship. They are often skilled at presenting themselves as perfect partners, showering their new romantic interest with affection, compliments, and attention. This phase is known as the "love bombing" stage, where they go to great lengths to make the other person feel special and adored.
During the initial stages of a relationship, a narcissist may appear highly devoted and committed. They might appear to be extremely attentive, giving the impression that they are deeply in love and genuinely interested in their partner's well-being. This can make it difficult for the other person to see any potential red flags or signs of narcissistic behavior.
However, it's important to note that this "idealization" stage is often short-lived. As the relationship progresses, the narcissist's true nature tends to emerge. They may become increasingly self-centered, manipulative, and emotionally abusive. Narcissists have a profound need for admiration and validation, and when they feel their partner no longer fulfills those needs or challenges their superiority, they may lose interest or engage in behaviors that betray their initial appearance of faithfulness.
In essence, while narcissists may seem faithful and committed at the beginning of a relationship, it is typically part of their tactic to gain control and admiration from their partner. As time goes on, their true nature becomes more apparent, and their behavior may change dramatically.
