What should i do after i got friendzoned by a girl that either liked me in the past, faked liking me and led me on or is just really flirty in general?

I dont know what to do, she friendzoned me and i don't know if i should keep talking to her (sometimes but not has much has i was) or let her go. Im not mad at her for friendzoning me, i cant force anything. Im just not sure if she liked me in the past and lost interest or if she was leading me on from the start. She is my class and we have mutual "friends", they're more like acquaintances to me tho, i dont hang out with them outside of school.
