What is the theme in Remember by Christina Rossetti?

The theme of imperfect love in Rossetti's "Remember" is an idea based on the more obvious and often used theme of religion in her work. To a poet so devoutly centered on her Christian faith and love of God, the love of a man must seem second-rate, at best. A question, therefore, arises about her sincerity in the relationship she has with her lover— on one hand, she seems honestly to love him and begs him to remember her when she is dead; on the other hand, she appears a bit nonchalant in her willingness to tell him to forget her just the same.
