These are just my personal feelings, no offense to anyone who believes differently:
DH and I were going to renew for our 25th anniversary. Not because we are trying to mask any issues or because we hope a renewal will "fix" our marriage but because our wedding was not the glam show I wanted it to be. But as I started putting ideas together, I was like nope! 75% of the people I would invite, I don't even like or associate with on a day-to-day, it is going to cost more than I am willing to spend, and I don't feel like being bothered. Our wedding was what it needed to be at the time. It was small, cheap and only our closest friends and relatives attended. I didn't need a glam show, that day was a great representation of who we are so no need to renew or redo anything.
Instead, we are going to take a really nice, 7 day trip and call it a day.
