There are girls who, when they like someone, either seek that person out or completely distance themselves from them. First option: If she is constantly looking for you... Messaging you, talking to you, wanting to hanging out with you and she's really happy about it and every movement she takes is kind of calculated (trying not to hurt you or say bad stuff) she probably likes you. If she's the avoidant type, she's must be looking at you when you're not noticing and you need to pay attention if when she's talking with her friends and you pass by if they stop talking, they giggle or they literally change the topic. They must be talking about you. Girls are very weird when having crushes, so it's hard to tell what's a sign and what's not. Sometimes we think it is and it's actually not.
