"Holding space" for someone in a relationship refers to providing emotional support and understanding for the other person, without trying to fix or change their feelings or experiences. It means being fully present and attentive to the other person's needs and feelings, and creating a safe and non-judgmental space for them to express themselves.
When someone holds that place for their partner, they are actively listening to them and validating their feelings, without trying to solve their problems or offer advice and are also being empathetic and compassionate, without getting emotionally caught up in the other person's issues.
Giving them that pause is an important aspect of any relationship, whether it's romantic, platonic, monogamous, polyamorous or otherwise and allows the other person to feel heard and understood, and can help to build trust and intimacy, helping to create a sense of safety and security, which is essential for healthy relationships.
It also means being able to hold space for yourself, and the ability to manage your own emotions and communicate your own needs, boundaries and to be able to take care of yourself emotionally.
