The couple’s marriage originally landed in crisis at the height of West’s erratic behavior. His public outbursts began last July, after he launched acontroversial bid for president of the United Statesanddivulged deeply personal detailsabout his family and marriage on the campaign trail and on Twitter. The frenzy prompted Kardashian to address her husband’sbipolar disorder diagnosisin arare public statement, asking fans for “compassion” and acknowledging their “complicated and painful” situation.

“Even if my wife wants to divorce me after this speech, she brought North into the world even when I didn’t want to,” he said. “She stood up and she protected that child.”

A source told PEOPLE at the time that Kardashian was “shocked that Kanye spoke about North at the rally,” and “furious that he shared something so private.”
