The word "adulting" is part of the bodacious street lingo the radical kids use nowadays. It means doing things a responsible, self-sufficient person must do. It includes going to work, folding laundry, waking up on time, vacuuming, running errands, and so forth. Soft, pampered, useless people—such as Millennials, Gen Z and Gen Alpha—use the term to describe anything productive that doesn't involve them sitting still and looking at a screen. When these infants trapped in post-adolescent bodies are overcome with the burdens of reality, they complain about "adulting." In some cases, this results in their inability to "even," whatever that means.
When you're the only one in a relationship acting like a grown-up, you might be tempted to think adulting is grounds for divorce. Living with a perpetual child is certainly a stress, but it's not a valid reason to end a marriage, as
adultery would be.
On the flip side, members of the coddled younger set might think being asked to clean a fridge is a heinous crimes for which no spouse can be forgiven. Imposed adulting from your significant other is not a valid reason to file for divorce.
Those who resist adulting can "OK boomer" more responsible people all they want, but life isn't always fun and easy. Those of us who lived through the tribulations of dial-up internet, flip phones, and mail-in bills don't want to hear it.
