Be aware when your partner is within listening distance. Then, when its appropriate, tell whomever you are speaking with how appreciative you are of your loved one. This could be as simple as saying, "You know, I still get butterflies sometimes when I run into my partner unexpectedly," to something as detailed as a play--by-play of the luxurious morning pampering you received unexpectedly a couple of days prior.
As long as you don't share personal confidences and are communicating with positive intention, regularly share with others how much you appreciate your dating relationship and see how it impacts your interactions - for the better.
