I'm glad you can vouch for this approach.
Acts of Service are probably non-sexual things. This is actually important to my brother. He expects his wife to have dinner on the table and the house somewhat in order when he gets home. That says love to him, (probably associating that with love because that's what we grew up with.) He and his wife had a rocky relationship because the two of them spoke different love languages.
When I was a kid, my mom use to point out how much my Dad loved us because he would check her car weekly, making sure the oil level was ok and the tires inflated etc. He wanted us to be safe. She was smart that she recognized those actions as a display of love.
Why is TET hot? Just look at his pic! He does have a way with words and is willing to put his emotions out there. He bares his heart. That's appealing.
As far as your situation, maybe you can get this book and share it with your husband, to use as a starting point in a discussion. As you said, your husband is a good guy. Y'all just need to get on the same page. The reviewer at Amazon had this point which seems to apply to you.
Perhaps relationships get rocky or arrive at an impasse because individuals are speaking a different love language than what fills up the "love tank" of the object of their affection...and a result, the recipient doesn't feel loved. It's not that they feel empty and unfufilled because love isn't being given, but because the language "spoken" is not something that registers to the recipient as a form of love.
Chapman says that if a person has a hard time identifying the main love languages, they've either been on empty for so long and are out of touch with their needs. For good or bad, my daughter is filling my maternal love tank right now.
I think you get the premise. In case you're in a relationship with someone who speaks a different love language, you'll know to ask the question and then to fill her love tank emotionally. I'm sure you have the physical part covered.
