Relationship advice needed

So basically this girl is giving me varied signs

1. She looks at me like at least once every day in class

2. She usually reply instantly, does initiate conversation sometimes

3. She does smile sometimes at me and does maintain eye contact. I've also noticed she moves or shakes her leg a lot more near me.

4. She does watch all my stories within half an hour

5. She definitely keeps conversation going a lot longer then needed 

6. She does seem shy sometimes near me but she's not shy in general at all

7. Recently my friend and her were in a group together of four and my friend told the teacher he wants me in the group and she also told the teacher she wants me in her group which was weird for me

I'm not sure if she likes me, and if she does why doesn't she say something?
