Idk what to do

[Pace]

Alright, so I was talking to the girl I like on facebook and out of the blue, she came out with the "Who do you like?" question. I told her "No, no, no" etc. Then she told me if she tells me, then I promise to tell her who I like back. I NEVER agreed to that and she tells me. I now feel like an butthead that I didn't tell her since I always get into promises and actually do them.

If she asks me tomorrow at school who I like, should I say her? Or just say a random name? Or just ignore her? I really wanna hook up with her, but it might get awkward and I might not talk to her for the rest of the year.
