Liv seems to have had a re-evaluation of her identity recently - esp. after her intense labour and early motherhood experience all whilst lockdown was happening.
Publicly it looks like Liv + Joe have had a very stable, almost sheltered, life - been together since high school, bought a home close enough to where they both grew up, Liv’s cushy influencer job (which Joe was intertwined with), married, baby… you get my drift. But it may have set them up for failure in the long run esp. when challenged with change as very little emotional resilience may have been built... I’m just nosey and speculating at this point of course.
I don't know why, but I'm kind of sad they've split - their family did seem so perfect.
