Need some help?

Girl has been looking at me for months and it's usually multiple times I night, I've seen her doing It from a distance, I've seen her looking at me from the corner of her eye etc. she seems to be quite a socially confident person. But Everytime I speak to her she seems to act strangely around me, for example, she won't say hi or anything she'll just look at me until I say it to her, and even then she gives me one word answers. Totally different around me, then you'll get the rare occasions where she seems to confident and can interact no problem with me, then she'll go back to acting shy around me. Rinse repeat, I'm not sure
