I don’t think you should hate either character, but rather seem them as both complex human beings who have flaws and have made mistakes even within their complex circumstances. Both have feelings that are valid, and you’re right, they don’t cancel each other out. Support systems for both of them would likely be able to help them function better as friends. I love how this book gives insight into mental health issues and how all consuming it can feel to a person experiencing it, so well as how alienating it can be for the people around them.
