Fear of abandonment in adult relationships stems from early experiences like neglect or loss, affecting how we view ourselves and others. Attachment styles, such as anxious or avoidant, can intensify this fear. Risk factors like childhood trauma or unstable relationships can exacerbate these issues, leading to signs like fear of intimacy, dependence, trust issues, and need for reassurance. Coping strategies involve therapy, self-awareness, communication, boundaries, and self-esteem building. Healthy relationships are key in overcoming abandonment issues, emphasizing support, vulnerability, trust, and communication. Recognizing these patterns and seeking help can lead to fulfilling relationships.
