Blade knew that he could finally get his eternal rest. Elio showed him his script, and even though he felt calm about it, there was a part of him that hurt knowing that. That part was because of you. He knew very well that you had already become too fond of him, you almost made him change his mind about seeking his own death, but it was impossible.
His choice was already made, and the script was in his hands. His death was already written, after so much time looking for his own demise, it was impossible to make him change his mind in just a few days. However, he chose to hide it from you because he did not want to cause you unimaginable pain, since he also held a deep affection for you even if he did not admit it.
However, his attempts to hide it from you were futile. You discovered from Kafka that his death was already planned, that he would eventually fade away into the wind and walk no more among the living.
He really hoped you understood, because of your knowledge of the pain he went through every day from the Mara curse. He hoped you understood better than anyone, because since you arrived you had helped him through his crises, however... It didn't seem that way. He saw the tears in your eyes, the resentment in your gaze and how disoriented you looked.
