I am writing a story about a very messy divorce and abusive situation. I am writing it from the man's point of view, where he seems popular, reasonable and kind. He reads as a very likeable character and I want the readers to like him. But at the end I want to reveal that he is an incredibly emotionally abusive man and everything you've read is not actually the truth, but a case of gaslighting.
I have an idea of how I want to bring in the ex wife's situation at the end, but it doesn't feel powerful or striking enough.
Any ideas how you would develop this? I want the end to be a big shock
