Hailey Baldwin signed up to be a wife, but she’s realized her role consists of more motherly duties than she’d like, RadarOnline.com can exclusively reveal.

Since marrying her husband Justin Bieber, she has noticed his behavior has regressed to “being an early teenager again.”

“She literally manages every aspect of his day and worries about his state of mind constantly, while he just kind of hangs around playing pranks on her and terrorizing her like a schoolboy,” a source told RadarOnline.com.

Hailey’s newfound responsibilities have only made her question what her life as a wife will consist of in the future, but sources say she’s afraid to express herself to the singer because “he’s so emotionally unstable.”

Readers know that Hailey and Justin got married in a private ceremony last September.

As RadarOnline.com reported, Justin, 25, and Hailey, 22, were aware that marriage wasn’t easy. In an interview with Vogue, they expressed the many hardships of their relationship.

“I’m fighting to do this the right way, to build a healthy relationship,” said Hailey in regards to her new life as a wife. “I want people to know that. We’re coming from a really genuine place. But we’re two young people who are learning as we go. I’m not going to sit here and lie and say it’s all a magical fantasy. It’s always going to be hard.”

Despite his flaws, “he wants to be the best possible husband for Hailey,” another source added.
