Just my take:
Yoko was struggling, as most if not all artists do at some point. Even the Beatles struggled at first.
She then connected with John through a series of events which landed her in swinging London among others who shared her strong interest (passion?) in the avant-garde.
I feel, if she never met John, we would not be discussing her based on her own merits. She would have either continued to struggle or perhaps experienced very little success.
I do not love her. I do not hate her. I am simply aware of her existence and her role in John's life.
