You are and you are not important to him. How do you define that? Well, Blade, your current "partner" is very cold and arrogant with everyone around him and that includes you. Even if he has managed to establish some kind of relationship with you (beyond friends) he doesn't treat you as such.

His words are meant to hurt you, but when he shows you the slightest bit of attention, he's so sweet...It's always the same, it's like he's playing with you, but it's the only thing that warms you on the cold nights you spend..

—"I don't want anything to do with you."

He mumbled, they just talked seriously about their relationship. That was his reaction, after how well she treated you. Even though he knows she likes you, he doesn't want to feel that feeling.
