Background: A successful marriage is a dynamic growing relationship in which both partners continue to grow to achieve personal satisfaction. Building a successful life depends on a successful marriage. Therefore, this study aimed to explore the components of a comprehensive model governing on-time marriages among Iranian married men. Methods: This study was conducted using a qualitative thematic analysis approach. Using a homogeneous purposive sampling method, 14 married men in Bushehr were selected and interviewed. The collected data were analyzed using the content analysis method. Results: The analysis of the data from the interviews revealed three main categories related to on-time marriage among men including having a family that supports marriage, a marriage loving character, and the conditions facilitating marriage. Conclusion: Following these findings, it can be argued that a successful marriage depends on three important components of personality, requirements, and family supporting the on-time marriage. Thus, the improvement of marital life also depends on multidimensional corrections made by taking into account these factors. Accordingly, some measures need to be taken to promote marriage among young people and make them interested in marriages. Furthermore, families need to support their children and provide facilities for them to have successful and on-time marriages. Finally, social institutions and officials are required to facilitate conditions for people to have successful marriages.
