An intimate wedding means guests are carefully selected.

What would you do if one of those carefully selected guests decided to bring a plus one even though you didn’t give them a plus on on the invitation? Would you explain the situation to the wedding guest, or would you allow them to bring the plus one?

That’ the situation this woman finds herself in as she plans her wedding, and she’s not sure how to handle it.

Read the full story below for all the details.

AITA for not allowing future SIL baby daddy an invite to our wedding?

I (32F) am getting married to my fiancé (35M) on November 2025.

Our wedding is small and intimate (50 people).

We are not having a bridal party, and we have a “No kids” policy, except for my teenage sister.

This woman and her fiancé are dealing with a situation.

Here’s the dilemma.

My fiancé’s sister (21F) is currently pregnant by her now ex (23M).

They started dating in November 2023 and got pregnant not long after.

We don’t know where their relationship stands, and it’s never been clearly communicated.

They are assuming that her future SIL and her baby’s father aren’t together.

The only thing we’ve been told is that they plan to “co-parent,” which feels vague and doesn’t clarify whether they’re officially together.

Based on how it was worded, we’re assuming they are not together.

I’ve never met him and I don’t plan to before the wedding.

She’s due about 2.5 months before our wedding.

So, they didn’t give her a +1 on her invitation.

When addressing her invite, I asked my fiancé: “Should we include him as a plus 1?”

His response was, “Nah, I don’t know him like that. So, why would we give her a plus 1?”

So, we sent her an invite addressed only to her.

The RSVP form also clearly states to leave the space blank if they don’t have a +1.

RSVPs go through a Google Form.

It’s clearly stated: “If you have a plus one, it will be listed on your invite. If not, please leave that section blank.”

But when SIL submitted her RSVP, she wrote her ex’s name on the +1’s name.

She submitted her RSVP.

She entered his name as a plus 1, even though it’s clearly stated she doesn’t have one.

I could’ve made separate forms for a guest with and without plus one, but that would just delay the issue.

Now we’re dealing with it ahead of time and not the week of the wedding.

So, it sounds like they are still together? Why doesn’t her fiancé just talk to his sister?

Let’s check out the comments of other people on Reddit to this story.

Short and simple.

This user asks if they can afford another guest.

This person makes a valid point.

Guests don’t get guests, says this person.

Finally, here’s more useful advice.

Why can’t some people respect invitations and RSVPs?
