Unlike most people, this break up did not happen because they fell out of love because of cheating or fighting.

It happened because they found out that way related.

Una and her ex live in Iceland, a small country with 300,000 people that are descendants of the same Viking family, which means odds are genetically related to most people around.

So when they found out they were related, we had to break up because family marriages have an increased risk of birth defects and small is the risk some prefer just not to do it.

So eight years later, she's dating another Icelandic guy, thanks to their released.

Not related in a country where everyone is from the same family.

Their advice is this.

Don't date your relatives.
