It sounds like he's singing to a prostitute he has fallen in love with.
He says she gives him love on her canvas...so her body is her art.
"You're the best I can do" - He can't seem to find anyone in the real world so he has to pay for it.
"And she told me that she loved me and she gave me my money back" - She had as much enjoyment as he did and decided not to charge him for something that was a mutual experience.
