But I am not sure Stephanie Meyer, as a writer, has a purpose for positively-written women or men who do not love.

I don't mean that she sees them only as hangers-on to male protagonists, but I've read these, and I've read her The Host, and all the time it seems to me that - amongst other things that make me wonder if I am a feminazi after all - the greatest passion she is able to characters with (male or female) is love. Romantic love especially.

Bella may have been a good character. but she was never allowed to have her very own plot. If you get what I mean? All of her plot was provided to her by other people, usually male, or male-accessed. These males were usually in love with her. This is a girl who has never really been alone, or sought something entirely for herself as an end that stands independently of other relationships not despite or inspite them but just of itself.
