Is she just being nice or is this flirty?

there is this girl at work who has a boyfriend (actually to be fair, I don’t know if she still is with him, I know it was like three months ago).

I’ve suspected maybe she likes me but I’m just leaning towards she likes me as a friend and so do I like her as a friend also.

ok so here is where things got weird. we were alone together (this does not happen often at all), then she starts asking me questions about my family and wanting to see pictures and showing me pictures of her nephew.

she said please... she was facing me and we were both sitting. I said no to the family pics and she said you’re so weird sometimes ___ playfully.

why does she care so much? after that, I’m leaning towards she is interested. but correct me if I’m wrong.

Is she just being nice or is this flirty?
