Girls, guys what does this mean?? Are they good signs?

Om recently ive really started to like a girl that ive been friend with for a while.. Soo recently ive tried to be more flirtatious with her.. Were always teasig eachother and stuff. She always complains when i dont say hi to her calling me a "jerk" and stuff and yesterday we went to a party and i was sorta looking at her and she told me to" stop" but in like a playfull way she was smilin too.. I always look around the room to see if i can catch her eye and u do most of the time
