A couple of times she has stressed that all she wants is the freedom to seek women, and stresses that she does not want a relationship. At most an acquaintance with benefits.

I also know her libido gets a boost when lots of women and men are interested online. Even if she doesn't plan to even give them the time of day. On the contrary her libido takes a huge hit if she feels rejected. Which I think explains the last two weeks.

So like you said there is something else going on, more with her self esteem. On multiple occasions she has said that she does not take the compliments of myself or guys seriously since we'll have sex with ANYTHING. So I wonder if her pursuit of girls is more of a vanity thing since girls are supposed to be more picky.

I don't deny that her orientation is bi, but her criteria to "allow" herself to be aroused is quite perplexing.
