Watched another happiness ted talk and he says people who are married/in relationships are happier than those that aren't.
Don’t remember the source but I think a study showed this was only true for the men.
I'm stretching the truth a bit but in my defense that ted talk did trigger me. He clarified that it was the quality of our relationships that made people happy not so much your marital status but all I heard was married people are happier. I responded by vowing to be more careful about what I watch or read.
I research everything and marriage alone does not make people happier. There is a spike of happiness right before marriage and for 2 years afterwards then you're back to your baseline happiness. Relationships matter but being happy before getting into one matters more.
