I FEEL THAT MY BEST FRIEND IS A PICKME HELP

Idek we study in different colleges even tho we are bestfriends, and there she has an "OTHER BESTFRIEND" Lets name them rara(my best friend) and riri(her other bestie) . Riri hypes up rara sooooooooo much that rara actually gets into character like so much confidence and she thinks every guy wants her, even if the guy dosent have any intention.

She flirts with a guy on text first and if at all he flirts back she literally will be like HE FUCKING WANTS BE SO BAD. like bro you started the convo as well as flirting first??

Commenting on a guy the way he could hear and if he turns she acts all surprised and start acting weird like shit bro he heard This happens not once but everytime.

She was never like this and i feel so sad that shes turning this Way

While we have our "we" Time we usually have a walk during evenings basically roads she tells "DID YOU SEE THATTT? HOW THAT GUY WAS STARING AT ME??" "WHY IS HE LOOKING AT ME" "HE SAW ME AND I SAW HIM" "HE IS CHECKING ME OUT" And atp I'll lose my shit bro in fact shes my best friend and shes with me for most of the things she becomes a different animal around xy chromosomes.

but while she says guys check her out she fucking would be covering her face with mask and burka LMFAO

I dont react anything else than giggling and blaming them cause i dont wanna sound jealous cause iam freaking not. But this behavior is bad and just because its me its fine, but if she does this with someone else they'd really give her a reality check not that she looks ugly or bad she is fine above average only but it dosent sound nice while a girl keeps saying about how a guy wants her even tho he literally dint tell out.

What should i do now tell me if this is a pick me behavior or am i not sound minded
