help

i have a crush. she's beautiful, everything about her is perfect. she has a crush (who is obviously an asshole) but let's not talk about that...
I was kinda skeptical about me liking her, but then i was like...oh, yea i'd smash.
i don't like explicitly being touchy with my crushes, i only just hold hands with them. she always gladly accepts to hold hands with me, i don't find that wierd thought. i only hold hands with my bestfriend and soul sister.
Here's where the problems start to come: number one, she is straight but would gladly fuck a girl, so bi-curious? that's not really a problem but she considers herself "straight" for the most part. number two, she never let's go of my hand, not untill we have to part ways. number three, she gives me mixed signals.
what kind? you may ask? she says things like "we look like a couple", "we look like we are dating", "i'd gladly leave my crush to go out with you". this might seem like a playful thing on her part, but she's the one who says all these things, i never once mentionned going out or dating when we hold hands.
i've only told two people about me potentially liking her and wanting to date her but she's honestly getting on my nerves becausei hate mixed signals.
