Attended religious services. No

Believed that marriage was important for happiness.Yes
It dosent hold true for my parents either they have been married for 27 yrs married at 18 and 19 lived together didnt attend church,were not U educated but did believe marriage was important for happiness.
I really think it depends on the couple and how hard they are willing to work to make their marriage work.
