So, I'm (M18) and I've had crushes (5) in the past with two liking me back but I couldn't read signs no matter how much I read about them online, only to later realize they did like me.
Anyway I like this girl (F18) now for about a month. Just for context she's not comfortable with anyone she meets immediately, so I've known her for nearly a year and has gotten to know me through her older brothers which I'm really good friends with, that's how I know her. So I think she's an introvert. I've teased her a few times as well.
Here's a list of signs in chronological order in a period of a month from when I started liking her. My gut says she's testing the waters.
---------
• We were joking about from aross the room and we held eye contact for at least 7s.
•Teased me a few times, then said "you don't know how to take me" with a small smile. As I couldn't tell if she was joking or not.
• Said have a good day
• Talked to me about a guy hitting on her and asking for her number. I asked questions on what he tried to do.
• Holds good eye contact with me when she's talking.
• She brought up an embarrassing moment which happened at an earlier time. I thought everyone would forget but she was the only one that quickly reminded me about it.
• Said "I love your suit" but so did a lot of other people
• Fixed a badge that was on my jacket chest pocket as she said it looked kinda weird.
• Smiles me when she now sees me.
• Looked back at me twice after she cut conversation from me while walking away from me in a crowd.
