i think my girl bestfriend wants to fuck me

so iam 18M my gf 18F and my girl bestie 19F are friends from school for around 10 yrs now. infact me and my girl bestfriend are friends even before i started dating my crnt gf and i think she wants to fuck me.

actually the thing is i and her were really close when i was single we were so close that we use to share literally everything and also got physical a couple times (just kisiing and making out not sex) when drunk, but as iam dating my girl for around 6 months i think we are loosing touch with eachother and are not close anymore.

but why do i think that she is sexually interested in me because my girl bestie is too possesive when i was single she used to act like my gf infront of the whole school so that other girls dont talk to me but somehow i got into a some relationships during my whole school life and and around 6 months ago started dating my new girl she got mad at me

and when i share my sex and makeout stories with my bestie she use to get really jealous and started acting wierd and really touchy with me around my gf like when she talks to me she leans in too much she touches me on my thies like really close to my dick by doing all this i think she wanted to make my girl jealous

but the thing is my girl finds it really hot and also turns her on, she told me that whenever she touches me she imagines me fucking her hard and making her cry, she even asked me if i want to fuvk her, and how would i fuck her.

also one day when me and my gf were having sex she asked me for a roleplay where she wanted me to take me bestie's name instead of her whle fucking.
