Every snake is just a little different and so what worked for your male is obviously not working for your female. It really does seem as though she is telling you that she has a need and now you get to be a flexible detective and try to figure out what that need is.
I have one ball python who is just totally different from all of the others and has needed a very small space and has needed to eat live (all my others get f/t). She has taught me the value of flexibility in husbandry approaches and has really taught me how to read snakes a lot better.
Sounds like this little girl of yours is asking for a much smaller space and then you might try to leave her alone for a week prior to attempting to feed again. Also, you might want to bump up her temps to 94 or 95F as an increase in temps seemed to help my little one be hungrier; probably because they digest faster at higher temps...?
Anyway, I bet if you did these couple of simple things then you'll achieve results. Good luck!
