There are many ingredients to a happy marriage and one key component which can lay the foundation for an everlasting relationship is the act of giving or generosity between the couple.
Though the quality of sex life is also a key predictor for happy relationships, help with household chores, empathy and understanding were equally important for a happy marriage.
Ultimately, the couples that reported generosity amongst them were five times more likely to be happier in their relationships. The act of giving more in a relationship and doing stuff to make the other one happy also influenced sex life more positively, thus making the marriage a happy one.
This study was conducted by the National Marriage Project and surveyed about 1400 heterosexual couples between the ages of 18 and 46.
