Is this just Friendly Or Flirty?

So this girl who randomly hits me at work told me that me and her have the same body types today, She spoke to me about the way my body looks before. Today me and her were working we were hitting eachother playfully when we either passed by eachother or just doing something but there was a point when me and her were close by making a smoothie and she bumped me with her hips. So this happend yesterday I guess my co worker long ago told her i had a girlfriend, i never talked about my personal life with her she then tells me "how long you been with your girlfriend", out of the blue, which scared the shit out of me. She also is a big extrovert she dances in front of people, she doesn't give a shit I'm an introvert, she also asked me to teach her Spanish before she left today, because i usually talk to this old lady who talks to me in Spanish.

Is this just Friendly Or Flirty?
