TL/DR: 39F feminist friend, alpha-widowed, low smv, ego-invested in beliefs and won't embrace redpill to help herself. What can I do, if anything?

I'm 26M, good friends with a 39F feminist. I care about her very much and I feel bad having watched her destroy her dating life with feminism. She's ridden the carousel and has a triple-digit notch count that she lost track of. She is definitely "alpha widowed" and won't settle for a guy less than 6'0, muscular, makes good money, smart etc. (top 10% guy) and can still pull quite a few of them for short term fun which certainly reduces her incentive.

On top of that, she's about 5'5, 285-300 lbs depending on the day, but has a pretty face. I know for a fact that her sexual market value is not quite high but I think if she lost some weight and embraced femininity she could still find a decent man close to what she is looking for for the long term commitment she wants. Problem is, she's extremely stubborn, brainwashed, and willfully cuts herself off from anything that has to do with redpill even though my redpilled advice has helped her in the past.

Clearly her ego is deeply invested in feminism, probably due to sexual assault at the hands of her father from a very young age, and I truly feel for her.... But blind adherence to anything is not good, and she is too stubborn to essentially understand how the redpill can help her steer her efforts to get what she is looking for. Any advice? I don't want her to be stuck with cats and getting pumped and dumped by alphas for the rest of her life.
