The "Insecure-Ambivalent" attachment style is characterized by anxiety and uncertainty in relationships. Individuals with this style often seek closeness but simultaneously fear rejection or abandonment. They may display clingy behavior and become overly dependent on their partners for emotional support. This attachment style typically develops in childhood, often due to inconsistent caregiving. When caregivers, such as parents, are sometimes responsive and other times neglectful, children learn to be anxious about their relationships. As adults, these individuals may struggle with trust and may experience intense emotional highs and lows in their connections with others.
