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.

So basically gossip girl but without the kid? YANBU!

This is happening in my family but not marriage. I think it’s disgusting as my sister and her partner actually have a child together. My mum tries to justify being with his dad as they are both the grandchild’s “Nan and grandad” but it doesn’t work that way does it!

it’s disgusting in my view but not against the law and nothing that can be done.

It’s hardly incest

No blood tie. Not incest and absolutely fine. Stop being so judgey.

I don't understand the problem. It might all get a bit confusing if the older couple had a child together, but otherwise, what's the issue here?

Hahaha. My ex boyfriend is my step brother. Our parents married. We are all just people. Incest indeed. Give your head a wobble

If they were brought up together, I'd agree with you. But two adults meeting who happen to be related to two other people on a relationship is a different matter.

I don't think it is disgusting at all. They aren't related. It is inconvenient and problematic but it isn't incest. Saying it is doesn't make it so.

It'll be bloody awkward if either couple split but it's not incest. Don't be ridiculous.

A bit Jeremy Kyle but not incest at all.

It’s clearly not incest.

My grandmother was a widow and ended up marrying her daughter’s widower FIL. Yes, technically my aunt and her husband became step-siblings, but they’d been married several years already themselves at that point. I imagine it could have been awkward if one or other of the marriages had broken down, but as they didn’t, it was a non-issue.

I don't think you understand incest

Not incest.

I actually know people who have this set up! In this case the older couple met first. Then they introduced their adult children to each other and they got together.

It’s not incest. Not even “borderline” as there is no blood tie. It’s not wierd either imho. It’s no different from a brother and sister marrying a sister and brother.

I think "step" relationships are different when entered into as adults. I am close to my mum's husband, but I don't consider his children to be my step siblings.

Couple date and bring their dd and ds up as step siblings. Step-siblings then have a sexual relationship and a child - weird and icky but not incest or illegal.

couple date and have a child. Woman’s mother and man’s father then also start to date - a bit eastenders but nothing actually wrong with it.

Don’t be so ridiculous none of them are related .

It is to incest what cows are to garden sheds.

This

Of course it’s not incest. The older couple probably didn’t even meet each other until they were old enough to have adult children themselves. That’s not remotely the same as a brother and sister who have been brought up together since birth.

I can’t see the problem. It might feel a bit weird, but they’re step relationships, (not biological or adoptive) so nothing incestuous about it. The birth of a grandchild doesn’t somehow change the existing relationships.

When we all Iived in villages and tribes, and repartnered due to high rates of bereavement, these situations must have been fairly common. Royal families and elite castes are still routinely related in several different places. It’s only the modern hoipolloi who expect to only have one connection to another family.

It’s not invest they are not related through blood or marriage.
I assume the 2 parents are not married as you didn’t say.
I’ve heard of far worse relationships.

Ha! Absolutely not incest at all, they are all adults, what are you on about?

Not incestuous at all. My ex colleague is married to his cousin so his mil is also his auntie. Now that is weird although I know it's not illegal to marry your cousin.
