"I'm so thankful that I got to spend that one final hour with him," wrote Alexis Morley on Instagram, sharing their last photo taken together

Adam Schlesinger's girlfriend Alexis Morley is opening up about her last memories with the late Fountains of Wayne musician.

On Sunday, Morley shared the final photo she took with Schlesinger, which showed the pair going on a "gorgeous" walk together on March 15 in upstate New York. The beloved songwriter would soon test positive for the coronavirus (COVID-19); he died on April 1 at age 52.

In a lengthy, emotional caption on Instagram, Morley wrote that Schlesinger had "grown open to, and eventually enthusiastic about" taking walks together — as long as they didn't refer to them as "hikes," she joked. The grieving girlfriend noted that early the next morning, he woke with a fever.

"We spent such a sweet week together, our roles kind of reversed because usually Adam was the one to take care of me," wrote Morley. "I tried to keep him comfortable, nurse him back to health, as we waited for the fever to break. We were sure it would—just like any other crappy flu. He said, 'I’m ok. I have my Alexis.' But 7 days later things got worse and I brought him to the hospital."

Not allowed to stay at the hospital with him, Morley said she drove home "terrified" but that they kept in touch by texting while "making cute jokes [and] feeling optimistic."

"He kept telling me how much he loved me and thanked me for 'saving [his] life,'" Morley recalled. "The next morning he was intubated. I never got to hear his voice again."

Morley then describes the moment she got a call at 3 a.m. from the hospital, telling her that Schlesinger "wasn't going to make it."

"I asked if there was any way I could see him (a cruelty of the pandemic is a strict ban on visitors)," she wrote. "They made special arrangements for me to be allowed into the covid unit: a low-lit, grim, heavy place; the medical workers and I obscured by layers of PPE."

Continued Morley: "But Adam looked sweet, peaceful, beautiful. I’m so thankful that I got to spend that one final hour with him ... I like to think he could sense us there, but he was deeply unconscious."

Not long after she arrived home after the visit, Morley got a call that her boyfriend had died. She shared a second photograph from that day, describing sunlight breaking through an otherwise gloomy day.

"Shortly after I arrived back at the house, Jordan, a male nurse who’d been so wonderfully compassionate in the covid unit, called to tell me that Adam had just passed, peacefully," she wrote. "He was holding his hand as it happened. It had been a dark, overcast day, but at that moment the sun came out for just a few minutes and lit up the entire sky. That’s the second picture..."

She concluded: "I love you so, so much, Adam."
