Does it matter if you date someone your sibling has?

Not happened to me, but would it bother you if say you dated the same person as a brother or sister of yours did?
It seems the 2 Beckham brothers Dorklyn and Romeo aren't speaking because Romeo is dating an ex of Dorklyns?

Ew yes I could never, imagine having sex with someone a sibling has. I honestly can't believe that out of everyone in the world it's necessary to date someone a sibling has.

Pedallleur · 12/04/2025 16:44

Keeping it in the family. Bryan Ferry married his sons ex girlfriend (later divorced her)

DenholmElliot11 · 12/04/2025 16:46

yes thats a horrid thing to do

mathanxiety · 12/04/2025 16:46

If it was acceptable for the ladies Spencer, it surely should be fine for the Beckham plebs.

There's a serious ick factor here - does the first Beckham think women he has dated are somehow his property?

girljulian · 12/04/2025 16:46

Unrelated but Dorklyn is the stupidest name ever. DORKLYN.

DustyLee123 · 12/04/2025 16:47

I don’t see the problem

Minnie798 · 12/04/2025 16:47

What a weird thing for anyone to do. Yuck.

JLou08 · 12/04/2025 16:48

I wouldn't date someone who had dated a friend. Dating someone your sibling has is even worse than that.

Ellmau · 12/04/2025 16:49

I think it depends on various factors. But in this case the previous relationship must have been years ago as he's been married to someone else for several years, so it's a bit ridiculous to object.

Sahara123 · 12/04/2025 16:50

I suppose it shouldn’t matter , but in reality 🤢

I think it’s meant to be a joke, it’s Brooklyn..

PeloMom · 12/04/2025 16:51

There are billions of other women he can date. It’s wrong to date a siblings ex

Yeah, it caused a bit of stir in a neighbour's family when one sister "pinched" her younger sister's boyfriend. She went on to marry him so it worked out in the long run and the rift between sisters eventually resolved, but it was pretty awful.

It's a bit grim, isn't it? Aren't there other men in the world?

PassingStranger · 12/04/2025 17:12

I knew someone whose ran off with her partners brother, it caused so much upset in the family.

Yeah, it's so weird

GreenWheat · 12/04/2025 17:57

I think it's grim and a bit seedy. It's like they can't be bothered to go out and find their own partner. And even if it does work it, it creates a weird vibe within the family. Just no.

SummerDaysOnTheWay · 12/04/2025 18:50

Dorklyn????

Mamofboys5972 · 12/04/2025 18:52

Me and my brother both slept with the same woman (mutual friend) and didn't realise until years later. Now we are both the butt of that joke every friendship gathering lol

Snorlaxo · 12/04/2025 18:53

It’s pretty gross but I think that there’s exceptions to this like ONS, breakup being amicable, many years in between…
Brooklyn is married so I wonder what Nicola (his wife) thinks

bettydavieseyes · 12/04/2025 18:54

I would never go there. Its just wrong.

Hungrycaterpillarsmummy · 12/04/2025 18:55

I think it's weird and crosses a line

SpringIsSpringing25 · 12/04/2025 18:59

Ewww, no, just no.

I’m going back many decades ago but one of my great aunts had an affair with her sisters boyfriend and married him. The sister who’d been treated so badly then went on to get engaged to a top class footballer of the day who’s sister (and husband) died in an accident leaving two children without parents. The footballer decided he wanted to bring the children up and my great aunt said no way, it’s them or me, so he chose the children and my great aunt died alone many years later with no one around her though I was in her life albeit from thousands of miles away. I’d taken over my mums role in her life when my mum died and it was all just horrible. I often wonder if what happened to her made her the woman who wouldn't take the children on. Meanwhile my other great aunt married the man she had the affair with and they were together for about 60 years. I don’t know how anyone can have sex with someone who had sex with their sibling.

Weepixie · 12/04/2025 19:20

And I’ve realised I had acquaintances through my husbands job and the bloke was married to his ex daughter in law and there were children from the father and son.

Then a neighbour who’s young wife died married her sister and brought the children up together.

Perhaps it’s more common than we think.

DustyLee123 · 12/04/2025 16:47

I don’t see the problem

I married my sisters ex (they were only together 6 months) but according to mumsnet I should be catapulted over the battlements into crocodile infested waters
