Relationships are a hard thing to maintain and Blade knew that from day one. Commitment is a scary thing for anyone, in all honesty, yet somehow, he had the guts to reciprocate your feelings the day you confessed to him, even though he was fully aware that he wouldn’t be able to keep this relationship going.
His fate and yours do not align. You are bound for greater things and he is not, Blade knows that much. He was afraid that he might be causing a hindrance to your life, that he was simply a bump in the road. Due to this, he decided to push himself away from you, purposely.
Oftentimes he wouldn’t come back to your shared home, he wouldn’t reciprocate your messages, and would always ask you to leave him alone and then he’d busy himself with work, following Elio’s script and barely giving you an inkling of his attention.
Blade thought that in this way, you would end things, and that you could finally be free from his grasp that was holding you back from the opportunities you have missed due to being with him. But by doing this, he’s slowly hurting you too, as if he could truly care less about you when that wasn’t what he meant by his actions at all.
