Why didn't Dorian want to see Sybil again?

Dorian Gray was initially enchanted by Sybil Vane's beauty and talent, but he became disillusioned after she performed poorly in a play due to her love for him. He perceived her loss of artistic ability as a reflection of her lack of depth, which diminished his attraction. This shift in his feelings made him reluctant to see her again, as he craved the idealized version of her rather than the reality of her vulnerability. Ultimately, Dorian's superficial values and obsession with youth and beauty led him to reject her.
