You don't have to lie to keep a secret. Not telling someone something is still keeping a secret, and is necessary in the scenario that you know something will trigger an episode in someone. There's also the factor of time. You may start talking about something previously left unsaid later on therapy, after you've established some trust. It's really not any different than how people engage in normal relationships. How I talk to a stranger is different than how I talk to a colleague is different from how I talk to a friend. You need to first build a rapport before you can talk about certain things.
