For many of us, our worst nightmare is our other half cheating.
For Sophie Tanner, this issue becomes slightly more complex after she revealed she had cheated on herself...
Before you begin to question how that's even possible, you need to cast yourself back to 2015 when Tanner married herself.
It may have been a fairytale wedding, but Tanner admitted on This Morning that perhaps she and herself didn't have a perfect relationship.
Tanner 'cheated' on herself with Ruari Barrett, a polyamorist who turned temporarily to monogamy while dating Sophie, in a relationship that lasted five months.
Eventually, Barrett dedicated himself to the same cause - in this case, himself - and had a self-marriage ceremony.
We hope this mess won't end in divorce. That would be a nightmare for Tanner, as both members of the relationship have an identical friendship group. Awkward.
Sologamy - the act of 'self-marriage' - is more common than you might think.
You might argue that self-marriage is pointless, given everyone is forced to stick by themselves through thick and thin, 'til death do them part. That's just what living is.
But self-marriage gurus say their way of life promotes self-love and a celebration of being single, outside restrictive traditions and expectations.
Speaking to Amanda Holden, Tanner said:
Self-marriage is about self-love. It's saying that self-compassion and self-care is as important as romantic relationships
It doesn't mean you're rejecting all other meaningful relationships in your life and becoming a nun forever more. It means you're rejecting bad relationships.
If only there was more self-love in the world, we wouldn't need ceremonies like this.
This is a statement which looks to raise the profile of self-love, saying it's as important as romantic love and doing it as a formal ceremony as anyone else would have a wedding.
Marrying yourself is a lifelong commitment to be responsible for your own happiness, so divorce is not an option.
