Kanye West and Kim Kardashian West were struggling with their marriage before he was hospitalized on Nov. 21 for extreme exhaustion, according to a new report.

A source tells Us Weekly that "it's just been hell for them" of late, specifically citing the weeks following her robbery in Paris.

Kim, the magazine said, has continued to struggle to feel safe and Kanye wasn't completely by her side, as he was on the road for his Saint Pablo tour, which he later canceled.

"The trauma of the incident made her more hesitant to do things," the source explained to Us, saying Kim was a fixture at his concerts before the robbery. "Of course it strained their relationship, because she hadn't seen him."

Kanye, too, reportedly became obsessed with his work.

"He would be up all night ranting about things," a friend of Kanye's told the mag. "They were fighting because he was impossible to live with."

He was also completely freaked out about the robbery. He relies on Kim to be strong, insiders have said.

"The mere thought of his wife being taken from him was too much -- it was like his mother's death," Kanye's pal said. "Seeing Kim close to death did a major number on him. It sent him into a tailspin."

Despite the fact that she went through a horrific experience in Paris, the report says she wasn't receiving the emotional support she needed from her husband.

"She felt like now she needed him to be stable and her rock instead of the other way around," a friend of Kim's said. "Kanye's so used to getting Kim's constant support and coding, but it's always about Kanye."

Since he was hospitalized, Kim has become his rock. A report in TMZ on Wednesday, Nov. 30 gave a detailed account of her typical day right now, which has her getting their two children ready for the day and then heading to the hospital to be by Kanye's side. Often times, the report said, she's at the UCLA Medical Center multiple times a day so that Kanye knows she's there for him.

Oddly, one of Us Weekly's source said Kanye's breakdown could ultimately be good for the duo.

"Kanye's behavior took a huge toll on their marriage," says the source. "But Kim feels relieved he is getting the help he needs. She thinks this is what it will take to save him — and help their marriage."
