An individual’s value system plays an important role in their intimate relationship or marriage. Most marital satisfaction research to date has been carried out in high-income liberal Western societies. We conducted an original quantitative empirical survey of virtues and values to examine their effect on relationship quality and stability in a sample of 511 respondents from Slovenia, a post-socialist society in transition. The results showed that respondents rated health, love, and safety at the top of their hierarchy of values. The key finding was that the presence of love was associated with an individual’s subjective perception of relationship quality but had no effect on the self-evaluation of relationship stability. In addition to love, both family safety and comfort were significant correlates of relationship quality while self-respect was negatively correlated with relationship quality. Only excitement was found to have a statistically significant effect on relationship stability.
