When I married a lifetime ago, I didn't take his name. No politics, no fanfare, I didn't like his name, he didn't argue. I stayed me.
Likewise, the children bear my last name. I briefly considered hyphenating them, as was a trend in my area, dismissing that as unnecessarily unwieldy and stupid.
My ex and I haven't lived together in over 8 years. I moved to my current address some three years after we split. Yet, some weeks ago, I started getting mail for him. Well, almost. The mail, mostly from realtors and hearing aid purveyors, is addressed to his first name and my last name.
He's never owned any property, as such, has never had any to sell. While he spent many of our years not hearing me, I doubt even the most sophisticated device would have provided a remedy.
Things change. He may very well need the services of a realtor. He may very well need to procure devices to aid his hearing.
Than again, it's not really he, the marketers are targeting. The person addressed doesn't exist, not here, anyway.
