Discuss the theme of blind love?

What specific characters are you referring to in this question, as in my opinion, there is no relationship depicted in the text that I would think of in terms of "love is blind". For the most part, we might see Pip's love for Estella as unconditional, but he is in no way oblivious to her faults or the way in which she has been raised. Nor, does Estella ever hide the girl she was ot the woman she's become. Please clarify.
