be caught in the middle

To be in a position between two or more sides in an argument or contentious issue, often leaving one without a clear course of action to satisfy either side. When my friends broke up, I was often caught in the middle, as each one complained to me about the other. Dude, Mom and Dad are fighting in there. You'll be caught in the middle if you go in now. I know that they're arguing about the budget because I walked into the conference room at the wrong time and was caught in the middle.
