"You're easier than nothing"
So from what I gather, there's a standard interpretation of this line that goes something like this...
"It's easier to experience/be with you than to experience nothing/be alone"
...and while I think this is valid in its own right, I honestly see it equally as the following...
"Nothing in life is easy but every moment with you is easier than easy (nothing = easy)"
He says "maybe I'm not in love" but then later "maybe I'm so in love" which to me reflects the dual meaning of the song's main refrain
Let me know if I y'all think I'm reaching, that's just the vibe I get from the song
