Yes. Yes. Yes.
I am a big believer that there are stories we need to tell for ourselves - to reconcile them in our bodies. I am writing a book that may go nowhere and I don't care. The outcome isn't as important as what it can do for you. Write. Write with passion and honesty and success will follow. I think the idea of manipulation in relationships - especially subtle progressive manipulation that we don't notice until it's over can be relatable to many.
