I met my SO in... I think it was 2017? Well after the rise of Tinder. We did not meet on Tinder, and neither of us have ever had an account on there.
We met through a social group for a game (not dissimilar to pokemon go), where we happened to play for the same team in the same area. We would have team meet ups occasionally and all go for coffee and to play the game at locations where there was a lot of things to do in the game.
I have not, and likely will never, use something like Tinder. Not only is it unlikely that my current relationship would fail, but even if I found myself single for some reason, I just couldn't care less. I've been through it all already. A LOT of shit relationships to the point where I'm kind of over it. If I didn't have my current relationship, I'm not sure I'd care to get into another one. To put it simply, my partner and I are so well matched that we've never felt the need to even raise our voice at eachother. I have an amazing relationship, we're both happy and comfortable. The only thing left to do is put a ring on it and wait for our inevitable demise. I wouldn't try to find any cheap substitute for them. Nobody has a chance of measuring up. I don't think that would be fair to anyone involved.
I have no illusions. I was profoundly lucky. So I don't expect anyone to "get" it.
I am with them, and they are with me, now, until the end of our days. Separate, and together.
