“Space Cowboy” was released, along with “Butterflies,” as a single from Kacey Musgraves' third studio album Golden Hour.

Kacey seems to be saying that she is okay with her significant other leaving for some time. She recognizes the fact that they had their good times together, but it is time to move on because it is the best for the both of them. He is claiming he needs space, and she is willing to give it to him because their love has faded.
