Should an ex wife go to the funeral of her ex sister-in-law?

If you really don't want to, no one can force you. But no matter how your marriage ended, you once loved this man, it's okay for you to show that. You only have one chance to say goodbye, so make sure you're sure about not going. Don't worry about other people, do what you wanna do. But you shared a life with this man, it's okay for you to say goodbye to him.
