In "In An Artist's Studio," what kind of relationship does the man have with the woman he is painting in Christina Rossetti's poem?

It is clear that this poem presents us with the
relationship between an artist and his muse. Note how, in a variety of guises, the
artist presents the same "one face" over and over and over, whether it is depicting her
as a "saint" or an "angel." However, note how Christina Rossetti presents their
relationship and the disturbing and rather sinister way it is
described:

He
feeds upon her face by day and night,

And she with true
kind eyes looks back on him,

Fair as the moon and joyful as
the light;

Not wan with waiting, not with sorrow
dim;

Not as she is, but was when hope shone
bright;

Not as she is, but as she fills his
dream.

Can we infer that the
muse is in love with the artist? If so, she is to be pitied, and deservedly so, for all
he sees in her is an art form to be endlessly copied and depicted in different shapes.
He has no care for her, instead "feeding on her face" in a disturbing fashion. She is
depicted not as she is in reality, but as nothing more than a male fantasy, "as she
fills his dream." Any personal existence or reality she can lay claim to is ignored as
she looks back at him with "true kind eyes" and waits to be ceaselessly
objectified.
