how long have you known your s/o, non single people?

I've been with my current computer for over a year now.

Over 20 years. We probably met through mutual acquaintances 30ish years ago, but that is lost to the mists of time.

Dated for 4 years. Been married for 45 years.

You win.

Married my high school sweetheart after 7 years and this year we are having 21 anniversary, so 28 years.

Met in 1986. Began dating in 1989. Married in 1994.

I think maybe around 1990-91. She was a good friend's little sister's best friend. Go married in 97.

ps. I think @Today@lemmy.world are showing our age just a little

We're not old, we're experienced. I love that I lived a 'be home by dark' childhood without a microchip.

30 years. Been married for 22.

11 years together, married for 5, poly for 8. Met when we were 18, first day of university.

21 years ago, married for 13 years.

I met him when I was 16, dated him for 6 years, and have been married to him for just about 50 years.

I met her just before May Day in 2009. Two days later we were going steady. Three months after that, engaged. A year after we met I moved in with her and a year after she proposed we were married. Well, church married.

We were protesting for marriage equality and refused to file a marriage certificate until it was the law of the land; but we had kids before that happened and then we got busy and we didn't actually get around to that part until the pandemic lockdowns. So ten years after we got married we turned in our marriage license.

I met her end of 2020 and we stated dating on the spot while I was on a business trip to South Korea during the pandemic.

9 years and a bit today, and we got married in January. And it's not like I wanted us to wait for it, it's just that I spent the first half of the relationship engaged in military service (they don't let you get married in the first 5 years where I was). God's great! 😁

About 40 years. We met for real when she was in 9th grade and I was in 10th grade. We started dating when she was 15 and I was 16. We got married 32 years ago.

Edit: Since it looks like we're the oldest couple in the thread so far: first date was October 5, 1986.

I think @Quilotoa@lemmy.ca has you beat with ~49 years

Together for 10 years, known for 25 years.

First date: Nov 2007 Married: August 2012

Known 35 years next month. Married 35 years in November.

fast marriage
- If you know, you know.

Together for 14 years. Known each other for 24 years.

Ahhhh, I'm old, so don't hold me to the exact year or anything, but fifteen years? Ish?

We knew each other before we were friends, so the exact year is kinda nebulous in my head

That's similar to what I was considering saying - my wife and I disagree whether we met when I was 22 or 23 and all the services we used to talk back then (IRC server, Skype, AIM) are gone, so there are no easily accessible records.
That said, I'm about to turn 38, so also fifteenish years is how long I've known her. We got married about seven years after that.
- I really wish there had been a way to export all the teamspeak records, because we were cracking each other up left and right.
  I did go through and copy/paste some of the Skype conversations, but that was just for some of the silly poetry and such that I wrote to her, and after I put it into a .doc file, I cleaned it up, and I can't remember if any of it had dates listed if I hadn't.
  This is why people keep diaries lol.

Since 2020, we started dating two years later. We're married now :)

15 years.

Dated. Broke up. Dated again a few years later. Moved in together. Bought a house and had kids.

7 years have flown by. Not married but with kids.

8.5 years. Coworkers for years, then decided to give it a try 3 years ago.

Well over a decade now, married for about 10 years.

Known him? About 20 ish years maybe closer to 25. I met him playing tabletop rpgs. Boyfriend at the time dumped me, he asked me out a bit after that. It's been almost 20 years now.
