So, I met this girl at the start of my school year, she's been my partner for almost every project in school. And she's also my lab partner and she collects TFs too. Lately, she's avoiding me. Very obiously avoiding me. When I tried to approach her to ask her something, she walked away in the opposite direction. When I asked for the other half of the report we were working on, she answered me angrily. When we had to change classes, she usually passes her stuff to me and asks me to put it on her desk but yesterday, she passed her stuff to the guy she told me she hated in class! I didn't do anything to offend her or hurt her. She just started acting this way one day. I need help dudes.
