Did I tell you about my friend? I want to cut off contact with her after she refused to read my book
What do you expect to accomplish by cutting her off?
I hope she'll be embarrassed about the situation, and hopefully will start to read it.
I can tell that you have worked very hard on your book, and are very proud of it, but reading a book is also a big time commitment, and some people might not be able to make that promise. You shouldn't cut off contact with your friend just because she can't or won't read your book. Even if she hates it, that's not a reason to end your friendship.
It's not just a book, it's a message that everyone needs to hear. I'm going to cut her off.
She has a right to spend her time however she wants. Maybe she's busy, or forgot, or just wasn't interested. You shouldn't ghost a good friend just because she didn't read your book.
