@Rat-In-Ur-Basement personally, if you're not intending on dating her, I don't think you should confront her about it. If she knows you're aroace, she's probably trying to get over her feelings for you, and unless she specifically brings it up, don't talk to her about it. And for the love of God, do NOT act like anything has changed or try to distance yourself from her because of this, that HURTS like hell. If she decides to tell you, reject her kindly but firmly. If she's a good friend, she'll understand.
