I was on the same hunt last month! The main thing to know is that the official title is actually 'I Am the Love of My Life,' not 'the love of my life.' That small change matters for searches. I scoured Audible, Libro.fm, and even my library's Hoopla. The production I ended up with was the one narrated by the author themselves on Audible. It has a rawness that a professional voice actor might polish away, which fits the memoir's very personal tone. There's an intimacy in hearing the author's own cadence and emphasis, especially during the more vulnerable passages. You can really tell when a sentence was hard for them to get out.
That said, the audio quality isn't studio-perfect—there's a slight echo in a couple of early chapters that sounds like it was recorded in a home setup. Some listeners might find that distracting, but for me, it added to the authentic, diary-like feel. If you prefer a more polished listen, I'd check if your local library has a version through OverDrive; sometimes they license different productions. Ultimately, the 'best' version depends on whether you value technical perfection or emotional authenticity more.
