Why is she doing this?

I have a person that I considered a friend in my life but the past couple of years she’s been ignoring most of my messages and responds seldomly so I gave up trying to be friends. But the messages I do send her she ends up quoting them and using them in her story or posts without tagging me or responding to me. They’re not like quotable messages either. She’ll just take a sentence out of what I said and use it. I also found out a guy I told her I was interested in and her are friends on instagram after she told me she didn’t know him. Why do you think she kind of uses my messages against me? Or do you think I should feel that way?
