When the words were written, what context they were written in, and how sincere they were is almost impossible to determine.
But the sentiment echoed in the wallet note does stand in stark contrast to that of his official suicide letter, in which he described Love as "a goddess of a wife who sweats with ambition and empathy".
"Frances and Courtney, I'll be at your alter [sic] ... [Frances's] life ... will be so much happier without me," he added, referring to the couple's daughter, Francis Bean Cobain, who was just one when her father died.
The release of the note comes a month after Seattle police confirmed that reports that they were looking into re-opening the case after they developed four rolls of film that had been sitting in an evidence vault for years were untrue.
Although a cold-case detective had reviewed the evidence, no new findings were unearthed.
Police spokesperson Renee Witt told the Seattle Times in March: "He dug up the files and had another look and there was nothing new."
Cobain was found dead with a shotgun wound in the head and across his body at his home on Lake Washington Boulevard on 8 April 1994. He was 27 years old.
The police investigation concluded that he had committed suicide three days before their discovery, on 5 April.
In 2013, a Seattle police department spokeswoman revealed that the department receives at least one request a week for them to reopen the investigation, though mainly through Twitter.
