Crushes

Okay soooo... the girl who made me begin questioning my sexuality and I chat a lot and have been friends ever since I first met her (and practically fell head over heels in love). I obviously at the time put the thought out of my mind and told myself she was straight. A few years on and we're chatting non-stop and she casually mentions that she's bisexual after I hint that I am. I think we flirt a lot and we're constantly talking about meeting up; I'm not sure if it's just dreaming me thinking she's flirting with me or if it's real, but she seems super flirty. If we do meet up, should I go for it? And from the bare minimum I've offered ( sorry 😂 ) does it seem she may like me too?
