When she calls you her "little brother"?

I like a girl. We work in the same company and got good friends over past couple of months. She is older by a year or two. She complimented my skin complexion and she likes to tease me "you have baby face" whenever I shave. She asked me why I didn't accept her Instagram follow invite I told her I quit it 6 months ago.(should I have asked for her number then or better yet gave mine?).

But here's the twist she sometimes calls me her "little brother"

(context: she has a little brother of around my age) and recently suggested she has a crush on someone else.

We often tease each other but always have respect for each other.

Now tell me should I run towards her or away from her (figuratively)?

Is she interested or not?
