"She had to separate from him . . . to get ahead and focus on her career," a source explains. "He was in trouble then and she couldn't help him. A lot of her songs were partially inspired by him. I know "The One That Got Away" and "Circle the Drain" are partly about him, as well as Travis McCoy of Gym Class Heroes. But she was young and it was a time in her life she cherishes."

The source continued to say, "They had good times. It's really sad. She could never help him and couldn't let herself go in that direction."
