Intimate partner violence can significantly impact individuals in many ways. This thesis aims to explore the complex experiences of what it is like for survivors to leave an abusive relationship which include transformation and growth. Part A presents an empirical paper using interpretative phenomenological analysis to investigate experiences of leaving an abusive intimate partner relationship for those with borderline personality disorder, also referred to as complex emotional needs. The findings indicated experiences related to being stigmatised, shamed and being othered whilst overcoming individual, healthcare and systemic barriers. Experiences also allude to facilitators supporting the leaving process while separating from complex attachments and reclaiming the sense of self during the healing journey. Part B presents a systematic review using thematic analysis to understand the experiences of post traumatic growth in the aftermath of surviving an abusive intimate partner relationship. The findings of this review uncover how aspects of post traumatic growth; resilience, gratitude/empowerment and self-esteem had been cultivated. These highlight the ways a shift in mindset from victim to survivor affirming, while using one’s own voice to share their story had supported post traumatic growth. The support and presence of others also supported with these aspects of post traumatic growth such as children, services and friends. This thesis signifies the magnitude of ways survivors persevered through adversity on a challenging journey to recovery and healing. The recommendations of this thesis refer to factors on a micro and macro level, providing a roadmap in improving outcomes for survivors across diverse communities.
