do i wanna fuck my female friend

I recently cut off a female friend because feelings kept getting involved and she was too immature psychologically and emotionally. I wanna fuck someone as I've been involuntary celibate for roughly 7 or 8 months, but another female friend is giving me mixed signals. I know if something were to happen between us it would be worth it in the end regardless of the outcome, and I'm honestly just scared to make a move. Take this very lightly; she is like a sister to me. By this I mean that she has been with me through really really rough times, and I am scared of making a move and ruining the great relationship we have. Tomorrow she's picking me up from my house at 6:30am and we're going on a 3 hour drive (both ways) into a different fucking state for absolutely no reason. I know she's done this previously with friends, and like if there has ever been any signs this is definitely the biggest.

Essentially,
Logical Thinking: Just stay friends
Me not wanting to be an incel: just slay that shit brah
