Why do girls ignore or not notice some guys they might like?

Anonymous
I know that there was this girl who did give me signs of interest every now and then. But on some days, she would just talk to other guys and ignore me but not flirt with them, and her friend usually talks to me. She would touch other guys but isn't touchy-feely towards to me but is receptive to my touching. Otherwise, she would tease/play around with me or do something out of place to get me to notice her. It's been back and forth, back and forth for months and I still can't tell whether she lieks me or not. Does she want me to come up to her? Or does she want me to leave her alone? Is she just messing with my head? I'm so confused that it's literally driving me insane. Lately, I've been getting angry about this and she doesn't speak to me. her friend makes a conscious effort to try to say hi every time she sees me. I don't know what's going on, so how am I going to approach this situation?

Well, I'm confused here. I know that the girl likes me and I like her back. Her friend is her roommate and it sounds like that either she likes me or something else, but what could I do?

even though she did ask me out to lunch once, I kinda declined cause I wasn't hungry. I asked her out this time, she told me that she wasn't hungry, she paused, and then she just mumbled about her roommate.

and well all her friend says is just hi whenever she notices me. I don't know.
