What inference can be drawn from these lines of Feste’s song in Shakespeare’s Twelfth Night?

He has developed a dislike for music

He is in love with the idea of love itself

He has lost his appetite for food

He wants sweet flowes in his court.

DUKE: If music be the food of love, play on,
Give me excess of it; that, surfeiting,
The appetite may sicken and so die.—
That strain again;—it had a dying fall;
O, it came o'er my ear like the sweet south,
That breathes upon a bank of violets,
Stealing and giving odour.—Enough; no more;
'Tis not so sweet now as it was before.
