Keep the wedding invitation, even if you weren't invited to their birthday

Finding out about a party you weren't invited to can make you reconsider a friendship faster than you expected. I understand the embarrassment. I still wouldn't withdraw someone's wedding invitation because they left you off their birthday list.
That's the question in today's weddingplanning thread. The poster invited a few of their best friend's friends. They weren't especially close, but the guests accepted and had been helpful with vendor recommendations. Then the poster learned that one was having an elaborate 30th birthday without them.
They wanted to uninvite the guests. After reading the replies, they edited the post to say they wouldn't. I'm glad they reconsidered, and I wish some commenters had made the point without insulting them. Admitting that something hurt is better than quietly turning it into a wedding-day grudge.
A nice party can still have a smaller list
We don't know how many people are invited to that birthday, what it costs, or who chose the list. Knowing it's elaborate doesn't answer any of those questions. A beautiful dinner for twelve can exclude more people than a casual reception for eighty.
Even if the birthday is enormous, you can like someone enough to invite them before you're equally close. The Reddit guests' willingness to come and offer recommendations sounds like something worth noticing, too. It doesn't guarantee a future friendship, but neither does one missing invitation settle the whole relationship.
On X this morning, a post about wedding exclusions argues that being absent from a guest list doesn't automatically mean you're hated. That isn't the same birthday situation, and I wouldn't pretend it is. I agree with the caution, though. There may be information you don't have.
An accepted invitation changes what happens next
Before sending invitations, you can decide that your wedding should be smaller and skip acquaintances. Once someone has accepted, withdrawing the invitation is a much bigger rejection. They may have booked a room, requested time off, or simply felt happy you included them.
I'd leave the invitation alone and give myself a little time away from the birthday photos. You don't have to decide how close you'll be forever before the wedding. You do need to welcome the people you've asked to celebrate with you.
This isn't advice to host someone who has threatened you, harassed a guest, or been part of a serious relationship breakdown. Those circumstances need their own decision. Missing a birthday invitation, by itself, isn't that.
If you've already said something, clear it up
If you complained privately to a friend, stop the conversation there rather than asking them to investigate the birthday list. Your mutual friend shouldn't have to negotiate an invitation for you.
If the guest heard that you were reconsidering, be direct. For example: "I was hurt about the birthday and reacted badly. I'm sorry I questioned your invitation. We'd still love to have you at the wedding." Don't attach a request to be included next time.
A longer pattern of being overlooked may deserve a separate conversation. "I feel like I'm usually the one making plans. Would you like to get together more?" gives the other person something they can actually answer. Asking why you weren't important enough for the party mostly puts them on the defensive.
At the wedding, I'd thank those guests for coming and mention the planning help if it was useful. They didn't earn their seats by sending vendor links, and they don't need to make up for the birthday with a bigger gift.
You invited them when you were excited to share the day. Unless something more serious has changed, I'd let that original welcome stand.
