Don't be guessing. That's a good way to make yourself feel crazy.
All you know at this point is that she's wondering why you are looking at her. If you are looking all over the room at the trash, then peeking at her, then the wall, then peeking at her, then the....
And she has noticed this behavior? She's going to wonder why you are doing that.
- If you like her and want her to know, tell her.
- If you like her and want to ask her to eat lunch with you or something? Ask her.
- If you tell her you like her or ask her to eat lunch and it turns out she doesn't like you that way? Say "Alright. That's cool. Thanks for being polite about it. I appreciate that" and walk away. At least then you know, and can start to feel better because you don't have to be "what iffing" it any more. Not the end of the world -- not everyone you like or date will be a long haul runner.
- If you like her and don't want her to know? Don't tell her, and dial down the peeking at her.
Keep this simpler on yourself.
