AIBU to think step siblings can be evening guests only at wedding?

My friend’s DD is planning her wedding. She has 3 step siblings who have only
been in her life for around 10 years, since she was about 19. Step siblings are younger (16- 22).

Bride & groom to be are considering a very intimate ceremony (20ish guests) followed by a huge evening reception. Bride to be wants the step siblings to be invited to the evening do. Friend & her DH aren’t happy with this. They think the step siblings should be considered the same as siblings.

IMO it’s fine to do this. Bride’s aunts, uncles
& cousins aren’t going to be invited to the ceremony. Siblings, parents & grandparents & best friends are the only ceremony guests.
My friend & I had quite a heated discussion about it. AIBU to think it’s fine to exclude the step siblings as they are not particularly close?

My husband has step brothers that came into his life when we was 18. He doesn’t see them as brothers at all and they weren’t invited to our wedding. Nothing personal and will be pleasant when he sees them but has no relationship with them. Ultimately up to the bride and groom

What the fuck are you having these heated discussions for? It isn't your wedding, or your friends for that matter!

The couple can invite whoever they wish to. All blended family dynamics are different and some people barely know their step siblings.

I have full siblings, half siblings and did have step siblings. I’d only invite full siblings.

I didn't even invite my one full sibling to m wedding ( as abroad) But the after party they were all invited. No body was offended

Yabvu if you can’t afford step siblings don’t get married especially if the DH wants them there. Sounds like an entitled bridezilla! Maybe he’ll see her behaviour and realise what she is before he takes the plunge/

It’s only the very small ceremony they won’t get invited to. That part normally isn’t charged per person. They will be invited to the dinner/party afterwards and that’s where the money will be spent. It has nothing to do with not affording to invite them. Just that they want just their closest family and friends there for the ceremony. OP didn’t meet her mum’s partner’s children until she was already an adult so they are not siblings in any sense of the word. Not biologically or familiarity. They really are just her mum’s new partner’s kids.

I didn’t make the cut to my own brother’s ceremony and found it so hurtful I didn’t attend the party either. I don’t agree with tiny exclusive ceremonies and definitely don’t agree with relatives (because yes they are relatives via marriage) being excluded from them. If you want to get married, as many people should see the actual marriage as possible otherwise what’s the point in inviting them. Being an evening only guest makes you feel like a little unimportant add on.

What kind of people are we? Please elaborate?

When I married I made it clear to everyone that I would be having the wedding I wanted and if anyone interfered we’d buggar off alone and do it without guests!
ultimately I think who is invited to a wedding is up to the bride and groom and wish everyone else would mind their own!
People are constantly moaning about who is and isn’t invited to weddings, if you don’t like it, don’t go is my attitude!

Very confusing response! Friend’s daughter is far from a bridezilla! Wedding is going to be quite low key, hence the very small ceremony. And it is the brides step dad who wants them there, groom barely knows them! You’re being nasty about someone you know nothing about.
And do you actually think people shouldn’t get married if they can’t afford to invite people they aren’t close to just because their parents got together? What if a couple can only afford to have their parents & siblings and no other guests? Not acceptable as their aunts & uncles might get upset? Some people get married with just 2 witnesses would you say they shouldn’t get married ? What a bizarre way of thinking!

The bride is allowed to ostracise anyone she wants. If she wants to make it clear to her step siblings that she doesn't consider them close family, let her cracks on.

For the sake of 3 places however I wouldn't risk tearing the family apart

They are planning a very small ceremony less than 20 so 3 is a significant number. The eldest SS has a long term boyfriend who she will probably expect to be taking as a plus one so could end up being up to 6 extra if they all have partners. Wedding is still a year away.

I had 2 half siblings and a step sibling I didn’t even invite. I didn’t invite my “father” either.

“Tearing the family apart” 🙄🙄 Christ, get the violins out.

These are adult step siblings. They probably don’t give a shit about not being invited. It’s just the mother of the bride wanting to keep up appearances.

Ladybyrd · 20/06/2026 09:46

It’s down to the bride and groom completely who they invite to their wedding. They also may have to deal with the consequences of hurt feelings though.

musicforthesoul · 20/06/2026 09:44

In general in ones like this I think the couple can invite whoever they want, but they really should consider if there will be knock on impacts they won't like. Not inviting someone makes a statement that you can't easily take back. Especially when its family. Its fine if you genuinely aren't close, less fine if you normally have a closer relationship that you expect to continue exactly the same afterwards.

In your friends case it's probably fine, I think you only end up with hurt if one side considers the relationship closer than the other which doesn't sound likely with the ages involved.

Not necessarily! Friend & husband could separate(my sister is on her 3rd marriage, doesn’t keep in touch with stepkids from 2nd marriage & her DC don’t either). Or when they are both dead the ‘children’ might never see each other again.

Exactly. If your friend’s marriage broke up tomorrow, would her daughter ever see her stepfather again, never mind his kids. I can’t really see why anyone would try to form a relationship with a parent’s partner’s kids if you met them at the age of 19, beyond what’s necessary for decent manners.

Your friend needs to accept that her partner’s children are just that to her children. They don’t see them as family. They have a family of their own. And her daughter wants people she cares about at her wedding.

I mean, its really tacky after 10yrs.

PollyBell · 19/06/2026 23:18

It is up the couple if people want to blend families it os the adults who did it not the children like any wedding the couple decides who they want at their wedding

Children dont have a choice who parents pair up with

Morepositivemum · 19/06/2026 23:14

While it’s the bride and grooms choice, I also agree it’s a bit cold to put them in a situation that’s generally a tick box to include someone who isn’t really close to you

DidntLikeTheEnding · 19/06/2026 23:10

That is absolutely ice cold. They should be there for the whole thing.

Why assume the step siblings consider the bride. Lose family?

if they are not close, then there’s nothing to tear apart.
