The aim of this study is to investigate the impact of the 
development process on the instability of emotionalromantic relationships in today's Iranian family. 
Therefore, the question of this research has this 
formulation: why and how the development process can 
become the foundation of instability of emotional 
relationships in the family? From a sociological point of 
view, through what mechanisms can the process of 
development cause the instability of emotional-emotional 
relationships in the family and destabilize the emotionalemotional relationships between husband and wife? In 
order to answer this question, the researcher has 
conducted a wide review of experimental and theoretical 
literature related to the issue of romantic-emotional 
relationships. The researcher, based on the methodology 
of "model adaptation", has investigated the impact of the 
development process on emotional-romantic 
relationships in the Iranian family of the seventies and 
nineties. Finally, the researcher discusses the implications 
of this research to understand the relationship between 
emotional-romantic relationships in the family and social 
structure. The process of development by creating 
changes in the position of women in the society, can 
affect emotional-romantic relationships and cause the 
instability of emotional-romantic relationships in the 
family.
