He could also try to crawl back and try to appease his ex and do whatever he can to get the relationship back. This line is a reference to "Art gets what it wants and art gets what it deserves", a line that first comes up in "Times To Die" to justify his existence. He thinks of himself as worthless but tries to cling to the worth of art as the reason he's allowed to be alive in his view.
All of my friends are getting married
All of my friends are right with God
All of my friends are making money
But art gets what it wants and art gets what it deserves
This comes back up in "Nervous Young Inhumans" as a motif clinging back to this, in which the "art" of the sentence is his ex/relationship. His justification for being alive is now his boyfriend/ex. In that song he deals with being bereft of this meaning, but in this song he deals with this yearning of going back to having a meaning like that, being the artist of his art, his ex.
