35-year-old woman involved with 18-year-old man?

I am 35, albeit very youthful in face and personality. And I’ve spent the past several months exclusively, happily, and increasingly seriously in a relationship with a fella half my age. Has anyone had an experience like this that did not end badly? Or for that matter, not end? I am specifically looking for stories and advice from older women (do NOT call me a cougar, ecch) who’ve had much younger lovers, not the reverse – that is, not men re younger women. Thanks, y’all. Try not to chuck stones.
