I can personally vouch for the groundbreaking new study about relationship satisfaction that finds it’s not who you’re with that determines a successful relationship but the dynamic that exists between you.

Samantha Joel, the study’s lead author, told CNN that she and her colleagues analyzed information on more than 11,000 couples and found that how satisfied you feel your partner is says more about the quality of your relationship than either of your personalities. “When it comes to a satisfying relationship, the partnership you build is more important than the partner you pick,” Joel said.
