Why did you abandon him and then come back to provoke him, when he forgot about him and their past? Why did you remind him of things he shouldn't remember and destroy the happiness he finally got?
No matter how deep the love is, how deep the hatred is, he has no hatred, only resentment. Blame him for letting him love him, blame him for abandoning him, blame him for not coming to see him, blame him for finally forgetting him but reminding him of the pain in the past, blame him... For letting him love him so much.
Sing a blooming song, he starts it, he ends it. When the flowers are blooming, where can you let go of your resentment? Let it go east, west, north, south, just to stop hurting you.
