Moriah Plath is opening up about her breakup with Max Kallschmidt in the new season of TLC's Welcome to Plathville.

In an exclusive clip from the season 4 premiere, Moriah is emotional as she confirms that she and Max are no longer dating.

"So, a couple weeks after I moved to Tampa, Max called me one night and just said he made a mistake," Plath says in a confessional interview. "I'm not going to go into details. Since then, I have been in a dark place."
