Has a woman (25F) message me (28M) and openly admitted she only wanted to talk to me for attention…when I ignore her she keeps texting me

It’s annoying. It’s gotten to the point when I don’t wanna deal with her I’ll just text her 3 or 4 times bc I know she’ll ghost and I’ll finally not deal with her for a couple weeks

But when I ignore her, she’ll keep wanting to say hi

We’re all adults, can’t we just grow up?
