You may think there's no formula for a happy relationship, but according to a recent survey from eHarmony and Harris Interactive of 2,300 people in relationships, there were several factors most "happy couples" had in common. Those 8 things included a healthy sex life, an equal balance of economic power, a lot of them had two kids, each person in the relationship earns at least $75,000 a year, they have college degrees, and they have similar political beliefs. Now although this is a common thread among those who consider themselves happy I wouldn't take it as gospel. At least that's what I'm telling myself since I consider my boyfriend and I extremely happy and we only check about 3.5 of the items on the list. I'll let you guess which ones, haha!
