For anyone wondering, avoidant attachment is a "relationship style characterized by a strong discomfort with emotions, a high need for independence and a difficulty feeling close with other people. (…) With an avoidant attachment style, a person might struggle with building long-lasting relationships or they might have a tendency to withdraw from the relationship if it feels like someone is getting too close."
