To tell my sister she can’t bring her husband to my wedding?

I’m getting married next May to my fiancee and we’re having a small wedding, 38 day guests and about 20 more in the evening. I don’t know what to do about my sister’s husband. Invitations aren’t out yet but it’s a family issue.

There are five of us siblings. My mum had three with my dad, then two with her second husband. My youngest half-sister is 26 and we’re really close, probably closer than I am to any of my other siblings. She’s been married before and has been with her current husband around 18 months. I have never really been close to him.

Tbh I have never really liked him, tbh, anyway, though. I think he’s a bit of a dick, but I know that isn’t really a reason to ban someone’s husband from your wedding. He’s not abusive and I haven’t tried to exclude him from family things before. He would normally be invited because we’re inviting established couples. My daughter is 9 and she’s the only child attending.

About six months ago he and my fiancee had a massive argument. He thought she’d deliberately left him out of a family barbecue and then messaged me saying I was letting my partner dictate the family. My fiancee replied and it all got quite nasty. I told both of them afterwards that it was ridiculous and said we should leave it. He has apologised once, but only for things getting heated, not for anything specific that was said.

What changed it for my fiancee was something he said to my daughter. He said “your mum won’t let you see your aunt as much once she’s married”. It wasn’t a threat, but I didn’t like him saying it to her. My fiancee now says she doesn’t feel comfortable having him there. I wasn’t there, she told me about it later that same evening.

My sister says her husband has been made the scapegoat for an argument that involved several people. She says she won’t come without him because it makes her feel her marriage is less important than mine. I can see why she feels that way, although I don’t think she’s entitled to bring someone my fiancee doesn’t want there.

My mum offered to pay for her hotel and childcare to attend. My sister says that’s made it worse because her family is asking her to choose between her husband and family. They paid a non refundable £180 hotel deposit, although I told her to wait. The venue has the capacity limit.

So I haven’t uninvited him because the invitations aren’t out yet. My fiancee says she’ll reconsider if he comes. I know never liked him, so I question it. Is it reasonable to invite my sister but not husband because of this, or am I making her choose between her marriage and my wedding? Mum told her we’re discussing it before I’ve decided.

It sounds like there is more to the argument story than you have explained here. Other people seemed to have been involved which means he may have had good reason to believe he was being excluded. If so why are you expecting a specific apology from him?
Also why would your fiancée be able to stop your daughter seeing her aunt after the marriage and not now? Is she not your daughter’s bio mother? Why does the marriage make a difference.

If you exclude him from the wedding then you are sending a message that he is not welcome at future family events and therefore your sister and her kids too! Is that what you want? Because you are setting a precedent here and can’t go back on it later. Also you would be making his predictions come true. That should give you cause to take a step back and examine your fiancées role in this

BagginBilbo · 19/09/2026 13:55

It all sounds incredibly petty.

An argument about a barbecue and then a comment about your daughter and your sister not seeing as much of each other. From your OP I'm starting to think that your BIL had a point about that comment too.

Draw a line under it all. Invite them both and have a fresh start to married life.

Grumpyoldcat · 19/09/2026 13:53

Either invite him or cancel the whole thing and go abroad to get married.

babyproblems · 19/09/2026 13:52

I think you should invite him. It’s not worth the drama. Just let it all go and invite him
out of politeness. If you don’t you really are making it all worse. I couldn’t live with this much drama. You don’t like him - oh well just tolerate and be civil. Life goes on

PixelatedLunchbox · 19/09/2026 13:52

What will your fiancée “reconsider”? Marrying you? Or how she feels about this brother-in-law? If it’s the former I’d wonder what else she’ll hold you to ransom for in the future. It’s your sister’s husband and he apologised for his part in the drama. Let. It. Go. Life is short. Don’t ostracise your sister’s husband and insult your sister. He’s not perfect, maybe he’s even a bit of a dick, but this manoeuvre of excluding him is not wise imo.

PrincessScarlett · 19/09/2026 13:52

You need to invite him. It's rude not to and will damage your relationship with your sister.

Sorry, I agree your fiancée sounds worse than sister's husband. Sounds like she is trying to sabotage your family relationships by reconsidering the wedding if he's invited.

I think you should invite him and try to all move on. It is quite rude to invite your sister and not her husband, it would be different if it were a boyfriend she hadn’t been with very long.
You don’t have to be his best friend but if you want to maintain a good relationship with your sister I would just invite him.
I also think if your fiancée is threatening to call off the wedding if he attends is controlling actually, dictating who you can spend time with isn’t ok.
Not really understanding the comment to your DD either, did he mean your fiance will make it difficult for her to see your sister?

this! Your fiancée sounds dramatic and controlling.

Coconutter24 · 19/09/2026 13:50

He has apologised once, but only for things getting heated, not for anything specific that was said

Why did he feel your fiancée had left him out of a family BBQ, was he the only one not invited? Did she apologise for any of the misunderstanding or anything she had said?

Invite him

fumingrightnow1 · 19/09/2026 13:48

Just invite him i think we all have 1 or 2 people at our weddings we would rather not to keep the peace. That's family

flixbus · 19/09/2026 13:45

I think your fiancee sounds worse tbh.

PollyBell · 19/09/2026 13:44

I don't see how your partner is any better really

Thanksforyourlackofthought · 19/09/2026 13:44

This is a lot of drama for absolutely no gain. Just invite him and preserve your relationship with your sister.

JHITRM77 · 19/09/2026 13:43

I'd think twice before not inviting him tbh, it will likely cause a rift that could last decades and could never be healed. It's just not worth it. I've seen it happen in my own family more than once, siblings fall out, don't talk for years then one passes away before getting the chance to make amends. People rarely remember the details of the original gripe. It sends a very big message not to invite family to a family wedding. You won't have to interact with him you'll be busy 🤷‍♀️

MagicThanks · 19/09/2026 13:43

You need to invite him. It’s one day, it’s not worth falling out over. I don’t have any relationship with plenty of people who were at my wedding, it’s not a big a deal as it feels in the run up.

PepsiBook · 19/09/2026 13:42

It will cause a huge rift with your sister if you do not invite her husband - how would you feel, if it were the other way around?

Sometimeslifeishardbutwecarryon · 19/09/2026 13:41

Jadedmoorhen · 19/09/2026 13:33

I would invite him, it’s your sister you are punishing if not

This. You and your new husband will be having such a lovely day, neither of you need even meet his eyes or if you do just acknowledge his presence with a smile. You can just immerse yourself in the joy of being with the family and friends that you do love. Hopefully they can both move on from this. (I, nor my family, can stand my brother’s wife but sometimes you just have to grit your teeth and attempt pleasantries even though it’s fake on our part. They've been together 40 years and I would have lost our treasured relationship long ago if he knew my true feelings). Good luck and have a brilliant day ❤️

Notsosweetcaroline · 19/09/2026 13:41

You can’t exclude him, thays scorched earth, it was a stupid argument. Move on.

LaurieFairyCake · 19/09/2026 13:40

Well she needs to consider the longer term, she’s literally marrying into your family and he is going to be at all family events for the next few decades.

Not inviting him creates a PERMANENT rift. Weddings are not about one day, people look at the photos and talk
about their wedding day at various points. If he’s not in the photos and not there and even WORSE if your sister isn’t there then it’s a permanent problem.

MrsChristianSlater · 19/09/2026 13:40

I don't think I actually understand what the argument is even about .. your DD won't see her aunt as much? So implying your fiancee is going to stop her? Which obviously won't happen unless your fiancee is as controlling as they're saying (red flag anyway!) or they decide they want to see you less... i must be misunderstanding?

BlueandtheGodofMischief · 19/09/2026 13:37

If you want a relationship with your sister then invite him. You don't have to like him but you do need to invite him and be civil when you meet up at the wedding and future celebrations. When it comes to the wedding you'll probably only see him fir 5 minutes if that as you'll be busy entertaining your guests.

Allmydays2 · 19/09/2026 13:37

I am so stubborn and ideally I wouldn't invite him ...but known the drama it would cause for life I would just invite and your fiancée can ignore him. Maybe he won't come anyway and I am sure your sister will have him on his best behaviour

Sparrowlass · 19/09/2026 13:35

The effects of not inviting him will last forever.

I am getting alarm bells from your fiancé too I am sorry to say. How much of this have you just got her side of the story on? She must know surely how much conflict this could cause yet she's still willing to put you through that?

Married couples are not invited to family weddings without the other half of them.

chirrupybird · 19/09/2026 13:35

There will be quite a few people there so your partner doesn't need to interact much with the husband they don't like. Just invite him it won't be a big deal for him to be there and it will be if he's not.
