My crush might like me back, but Im not sure

So, for the last couple of months I've kinda had a crush on a close friend of mine. She's not my best friend but she's really close, we sometimes talk the night away about random subjects in our 4 am thoughts. She's also one of the two people I have come out as genderfluid, and she was very supportive of me. My best friend knows I like her, actually knew that before I even told her, and recently she has been telling me that she thinks my crush likes me back and has been pushing me to confess, but I don't want to raise my hopes up just to be rejected and lose a close friendship. My crush is Pansexual, so my gender isn't much of the problem here. So, should I confess?? Or should I just stay quiet?
