There’s lot so things we CAN do to express our love and listening is a big one.  In a podcast by Tara Bracht titled Sacred Pause she said, “The deepest expression of love is a non doing presence.”   Find your heart, and put your hand there, bring your breatlove sunseth there.  And with that awareness listen to your partner.  That might then lead to a hug, or doing something kind for your partner, but it starts with deep listening.
