I think you are right about that static situation. To be a static character means that one does not change. Estella does not change throughout the story in a few ways and these can be proven by pulling quotes from a variety of places.
First off, Estella happily torments Pip... throughout life. In the early chapters (8-10ish) she torments him for calling jacks knaves and for his work boots. It is as if she knows Pip has a crush but will not under any circumstance be kind. In chapter 44, she is bent on marrying Bentley Drummle and when Pip tries to scold her for it, she knows she really has no love for him but just the desire to wreak havoc on men. Thus, her goal is achieved in two ways. First, Pip can't have her. Second, Drummle will live in a loveless marriage. Try the last 2 pages of 44 for quotes. In chapter 58, when the two meet up again, she is still at the very least cold to Pip. She discusses the place with him, insists in the end they will continue as friends apart. Using that language must drive the dagger of torment deeper and deeper into Pip.
Estella's beauty never fades. She relies on this beauty. You can see her unchanged beauty in chapter 58:
"[Her beauty's] indescribable majesty and its indescribable charm remained."
Many say that beauty is only skin deep, but with Estella is it really? Is there something in it and her upbringing that make her contantly intollerable of the opposite gender?
