How does a girl feel about me?

I like this girl and tried asking her out, but she claimed she has a boyfriend. We communicate on Instagram’s DMs and I sometimes show them to a female friend to ask for her opinion, and she claims the girl is sorta flirty and maybe even likes me

Thank you for all your opinions. I have decided to stop pursuing her and to just try and stay friends
