The rapper was hospitalized for exhaustion on Monday after a series of erratic incidents

The fallout of Kim Kardashian West‘s horrific robbery at gunpoint nearly two months ago in Paris has had its own impact on her relationship with husband Kanye West — and the rapper’s recent breakdown and hospitalization are creating additional strain in their marriage, a source tells PEOPLE.

“Kim has had a very rough time since the robbery,” says a source close to the reality star, 36, who has been keeping a consciously low-profile lifestyle since early October. “It hasn’t helped that Kanye has been touring. Their lives have been quite chaotic. It’s been very trying for them both and not a good recipe for a happy marriage.”

Before the robbery, the source says, “Kim [was] usually the more stable and strong person in the marriage. Kanye is used to leaning on her. Since Kim has had her own issues to deal with, the roles have been reversed. Kanye has had to stay strong to support Kim, and it’s like he can’t handle it anymore.”

The source adds that the 39-year-old Grammy winner, who stands to lose millions after he canceled 21 dates on his Saint Pablo tour, “is totally wiped out from touring and just can’t handle it emotionally.”

And with his wife and support system taking a step back in order to overcome her recent trauma, the source says, “It’s like Kanye is falling apart now, because Kim hasn’t been able to give him her full attention.”

Kardashian West, who was in New York City on Monday night to honor her late father at the 2016 Angel Ball, returned to Los Angeles to be by West’s side as he recovers from his physical and emotional meltdown.

Friends and fans are also sending their support, with R&B singer Janelle Monáe, for one, tweeting that she is “PRAYING FOR KANYE. PRAYING HE HAS THE RIGHT ENERGY SURROUNDING HIM DURING THIS TIME. SENDING PEACE AND LOVE.”

As for Kim herself, a source told PEOPLE earlier this year: “She has a lot of faith in him that he’s going to see his way through whatever kind of conflict he’s having internally or externally and that it’s all going to work out well. She understands his process as an artist and as a person, and I think she just has a lot of faith in him.”
