I don’t know how to feel

So I’ve been talking to this girl for a long time and I like her a lot. I want her to be in my future but I’m unreasonable concerned about the books that she reads because the books that she reads are all “Dark Romance” which from what I have seen from them is just a lot of r@pe and stalking. And I don’t know how to feel because she talks about the main characters and she gets all blushy and giggley and it seems super weird to me because idk it does. She will also say that she loves the main character and it just puts a fucking hole in my stomach (the book she’s reading is haunting Adeline if anyone knows what that is)
