She is gay
Friendly if she does it to others , if only you then she likes you
Idk. Sounds a lot like flirting to me. I'd pay attention to see if she does that with other people too but idk man I do that a lot when I flirt
She is a cannibal and is just checking out how tender you are!
I would say yes!
Affectionate, certainly. Maternal or romantic, exclusive or just inviting you to be part of her circle of friends? Touch her on the shoulder first next time you meet, and smile.
…ask him. honestly and openly.
