Eh, I dunno. In theory, the person matters more than the age, and I married a woman younger than me by a good margin over a decade ago, so I know that age gaps can be overcome.

That being said, she was still in her mid twenties when we met. So a grown-ass woman, not barely a woman. She has a kid, had worked and gotten partway through college (health issues stopped that), so this wasn't someone without life experience.

Talking to younger adults can be a chore tbh. There's plenty that are great, have their self as figured out as it gets, so they're good company. But there's plenty that aren't good company because of pure inexperience. I was a fucking chore when I was in my early twenties, that's for damn sure.

Realistically, now that I'm about to pass the half century mark, I don't have the energy to sort through someone that isn't fully integrated with themselves and ready to be a full partner. If my wife and I fell apart, I probably wouldn't have the energy to date anyone lol. I can't imagine settling down with someone that isn't settled down themselves, so I can't imagine anyone much under thirty matching with me now.

I wouldn't reject someone just because of age, but it's a pretty damn big factor in other traits. Fwiw, I would date about the same years upwards as well. Someone much past 70 isn't going to be in the same phase of life, but I wouldn't reject them outright. So there's that.
