To think this is not far from been incest AIBU

[Sandysunnyhotbeach]

I know a young couple in their early 20's who have a young son, who is nearly 20 months old. The Girl's mother is dating her boyfriend's dad. So if they were to marry, they will be step brother and sister, her mother will be also her stepmother and also mother in law, if the girl marries her boyfriend.
I know there is no blood relation, only by marriage, but think this is werid and borderline incest.

Don't be silly. This is not incest in the slightest. 100% zero incest anywhere!

You what?

This!!

Not incest but a bit weird. I have a much bigger issue with first cousins getting together, as two of mine have 😣

Yabu

I hope you don't go around in 'real life' gossiping about these peoples 'incestuous' relationships as well. Nasty false rumours can cause a lot of damage.

It’s completely fine and nothing like incest whatsoever. I suspect it’s not an uncommon scenario.

They are not blood related in any way so not incest. They're also adults and this is their decision to make.

Exactly this.
Op, you are quite mad.

Your OP says but think this is werid and borderline incest.

You absolutely are judging.

Were they raised as brother and sister? If not then what's the issue? I know of similar circumstances. But the couple were together a while before they're parents got together. But the parents wind them up saying your sister/brother instead of saying they're name which is pafetic.

It's nothing like incest, it might be a bit out of the ordinary but not incest. I thought you were going to talk about first cousin sexual relationships.

YABU, blimey. There’s nothing wrong with this, they’re all adults. There’s no abuse of power situation like with a child and a step parent, or anything like step siblings being brought up together. Get over yourself.

I think it's sweet. Happened in my family too. My aunt married the father of her daughter's husband.
Hardy incest- no blood relation.
In my family it worked really well- everyone was close and had posittive relationships.

It must be time for this then

I get how it initially feels weird, but providing they all met after the young couple were grown ups, there's nothing wrong. It would be different if these families became involved whilst the young couple were still growing up.

"think this is werid and borderline incest."

It's horrible to think there are people like you who judge like this.

Why is this disgusting? I don’t get it.

Your post trivialises the horrors of incest.

I imagine with the increase of divorce, separation, blended families, etc this situation will become more common over the next few years. Not incest at all, but mirror what others have said if they were brought up together that'd be weird!

One of my closest friends is dating her sons gorlfriends Dad.
Not weird. Awkward if either of the couples spit.

They're not related. So no, it's not incest.

And it's hardly surprising that is two people who have similar life values and life outlook may have other family members who also shared these values and get on well. Just the same as a friend of a friend is probably more likely to be a good love match than someone you meet on a blind date.

It's nothing like incest! No blood relations and neither couple has been brought up as 'family'. What an odd thing to think.

This happened in my family. My parents married first and my grandparents married a few years later after being widowed. I was a bridesmaid . No-one has ever considered it incest, just a vaguely interesting anecdote...

We know a family where the DH's sister is married to DW's brother!

So no complicated family rota at Christmas!
