According to Gary Demonte Chapman, a relationship counselor, author of The 5 Love Languages, and director of Marriage & Family Life Consultants, Inc. http://www.5lovelanguages.com/about/gary-chapman/ there are five love languages— the ways we demonstrate our love to others.
The first is acts of service—doing something for someone else. So, yes, doing the dishes for your significant other absolutely does say, “I love you!”
The second is gift giving, which is important not to confuse with materialism. The thoughtfulness that goes into gift giving says, “I love you!”
The third, physical touch, is a very common love language. Hugs, pats on the back, holding hands, ect. says, “I love you!” The right touch fosters a sense of security and belonging in any relationship, not just romantic.
The fourth, and my personal love language, is quality time. Nothing to me says, “I love you,” more then when someone sets aside time for a distraction free conversation or quality time for an activity like taking a walk together.
The fifth, and final love language is words of affirmation. For some people, hearing the words “I love you” means more than you know.

With hope and healing,
