WWE promos have better love dialogue than Twilight, so it's actually better than nothing.
Also, you don't say it out loud, you take the context where the character is currently at, and channel the most believeable response that character can have. Know the character (context) and yourself (your communication experience), and you'll know what the character needs to say at that moment. Master inferring from the context, and the dialogue will be easy, because it's the job of the storyteller to communicate from the text to the reader.
