We’re all familiar with the complaint that Valentine’s Day has taken on too much of a material focus. And looking at it objectively, it’s pretty silly to assume that our feelings can be sized up in a dozen roses or a fleet of pink balloons. Yet, cards and chocolates aside, this heart-filled holiday is, for many people, an excuse to take time to feel their loving feelings for their partner. A lot of couples seize the opportunity to table their respective issues and really appreciate the person they’re with. Research demonstrates that gratitude helps couples by prompting a cycle of generosity.
