Make your partner your muse—and your bond lasts longer. This is what psychologist James Pennebaker found when he asked volunteers to write deeply about their partners for 20 minutes a day for three consecutive days. Three months later, the "romance writers" were 25 percent likelier still to be dating than those asked to write about other things
. Expressive writing leads to the habit of expressing how we feel, and by articulating our feelings, we reinforce
them. For months after writing about their relationships, people were more emotive—using words like "happy," "sweet" and "love" more often—even when texting their partners. The best part: Their partners reciprocated.
