WHAT WOULD YOU SAY TO A GIRL WHO AVOIDS EYE CONTACT WITH YOU BUT STILL TALKS TO YOU?

theres this 1 girl in my cl named erika. so whenever she talks to me or i talk to her i wouldnt say she TOTALLY AVOIDS EYE CONTACT but it kinda seems like her eyes are somewhere else but she still talks to me though... with other boys she has complete eye contact so idk if shes shy around me or she just plain out doesnt like me? i wouldnt say she doesnt like me i mean she does talk to me whenever she gets the chance to and same with me?
