I [36F] just broke up with my partner[42M] of five years, and it was severely underwhelming. Thoughts?

I [36F] just broke up yesterday with my live-in partner of five years [42M].
The breakup talk lasted about a minute and a half, and then we both went back to surfing our phones. For real.
I know we have both been burned out by the seemingly constant bickering, lack of sex, and growing apathy between us. But this was by far the most apathetic breakup I've ever experienced.
We were together for five years in a very serious, monogamous relationship, and it took a minute and a half for it to be all over.
I'm curious to know if anyone else has had a really, really underwhelming breakup with a long-term partner?
Most of the time, when I think about long-term breakups, I guess think about sobbing, or introspection, long talks about how the couple tried, or... just anything involving feeling. This breakup just feels.... so surreal.
Seriously, has anyone else had a relationship that just imploded in apathy? I can't be the only one?

tl;dr: My relationship just imploded in apathy in a minute and a half. Am I alone in this experience?

"Hey, I'm not happy and wanna breakup"

"Really?! Gosh I was feeling the same way and was gonna bring it up"

"Cool!"
