This dissertation investigates the growth trajectories and prosperity of individuals born in mixed-orientation marriages (IBMOMs) in contemporary China, aiming to uncover how these family structures impact their lived experiences and overall happiness. Through qualitative analysis of in-depth interviews with IBMOMs, the study explores their emotional experiences, coping mechanisms, family dynamics, and prosperity strategies on their life trajectories. The research identifies that IBMOMs’ emotional responses are significantly influenced by the timing of their parents’ LGBQ identity disclosures and the nature of parental relationships. And heterosexual spouses’ long-term psychological state often leads to profound distress for IBMOMs, affecting the formation of their selfidentity and views on interpersonal relationships. Additionally, the study highlights that supportive family environments, effective coping strategies, and economic stability are crucial for IBMOMs’ prosperity. Finally, the dissertation advocates for broader societal reforms, including the legalization of LGBQ marriages and improved public understanding of LGBQ 2 issues, to reduce the challenges faced by IBMOMs and promote a more inclusive society.
