If you are dating a girl at school who only uses eye contact when she talks with you is this because she is trying to be rude or because she doesn't like you?
Most likeyly, she hates you, or she is annoyed by you. It
depends on the way she uses eye contact, i use eye contact with
everyone just because i want to show them that i can be attentive,
but if she throws a glaring look at you while talking maybe you
just hit an uncomfortable topic, you can just be honest and tell
her that it makes you feel uncomfortable when she looks at you like
that. Hope this helps
