I don't know how it's going to be portrayed in this series, but I doubt she loved the Prince enough to do that anyway. The Emperor's obsession with YGF caused him to neglect court affairs, eventually leading to a power struggle for central control of the government involving the general An Lu Shan and YGF's brother. YGF and her brother were blamed for the rebellion and the Emperor was forced to execute them. Soon afterwards, Xuanzong abdicated. Yes, it's a very sad story.
