Infidelity is a breach of trust that can manifest in various ways within a relationship. While physical affairs may be the most commonly associated form of infidelity, it's crucial to recognize the different types that can occur. Emotional infidelity involves forming deep emotional connections outside the relationship, online infidelity entails engaging in intimate interactions through digital platforms, and fantasy infidelity encompasses romantic or sexual fantasies about others. Financial infidelity and physical/emotional neglect are additional forms that can cause strain and undermine trust. Understanding these diverse types of infidelity is essential in navigating the complexities of relationship betrayal and working towards healing and rebuilding trust.
