Express gratitude to the one you love.

Research shows that gratitude is one of the most powerful — and efficient — ways to strengthen a romantic relationship (or any relationship, for that matter). Gratitude is relationship-strengthening because it requires us to see how we’ve been supported and cared for by other people.

Take Action: Celebrate the one you love by detailing all the things that you appreciate about him or her. Cut out a dozen paper hearts, and write one thing for which you are grateful on each.
