Feeling betrayed by your partner even after sharing a beautiful time with each other can be a devastating and heartbreaking situation for most individuals. If you are also one of them, then you might feel relatable to the grief that arises from infidelity. The first thing that shatters is your deeply built trust in your partner, and the second one is your self-esteem. Living a normal life while dealing with such a traumatic experience might feel like walking barefoot on burning coals. Expressing sexual desires to others or romanticising each moment with them while being committed is what truly explains infidelity. In fact, in today’s digital era, texting, approaching others for intimacy, or even emotionally building a relationship with them while being in a marriage or relationship, also falls under infidelity. However, have you ever wondered what the psychological factors are responsible for this? Certainly, dopamine rush, emotional voids and lack of empathy are the major root causes of infidelity, sabotaging the beautiful bond that was once built on trust and love.

Key psychological factors responsible for infidelity in relationships. 

An imperfection lying beneath every relationship is what makes your partner fulfil their sexual or emotional needs outside the relationship. For a deeper understanding, go through the points mentioned below, demonstrating the specific psychological root cause for infidelity. 

Specific attachment styles: Does your partner have anxious or avoidant attachment with you? Let’s understand the meaning of both. Anxious attachment people often remain in fear of being abandoned, due to which they approach others to console them, eventually making cheating justified for them. On the other hand, avoidant attachment people love their independence, due to which they want to maintain a particular distance from their clingy partners. This is the major reason why they chose to cheat on their partners instead of putting in the effort to have a healthy conversation. 

Feeling emotionally abandoned: A constant reassurance and providing emotional support to your partner is what keeps your relationship going for years and years. However, when your partner feels emotionally disconnected from you due to your avoidant or always busy nature, then they find no shame in cheating on you. According to psychology, when an individual’s emotional needs are not heard or valued, then they approach others who provide them the same comfort and warmth they needed from you. This gives birth to infidelity, destroying your inner self.

Boredom and neurological rush: According to psychology, individuals who prefer cheating on their partners crave new experiences, especially in sexual activities. Due to this, they gradually start feeling bored in their already existing relationship for a long time, resulting in betrayal from their side. Chasing novelty, their brain is flooded with dopamine, making them feel sexually attracted and interested towards others. In the desire to experience new and benign moments with others, a beautiful and long-term relationship came to an end.
