Every person wants to be heard and felt understood in a relationship. Poor communication between you and your partner can lead to misunderstandings, arguments, and a lack of emotional connection. When partners struggle to communicate effectively, it can cause frustration, resentment, and a feeling of being disconnected. This can ultimately lead to a relationship being destroyed since communication stands as one of the most important pillars in a relationship. This pushes a relationship to its end and hence, your partner may want to leave your partner.
