What happens when you discover that you have a different relationship to this new person than your partner does? What happens when it is no longer 'we' but instead a complex 4 relationship situation (AB, BC, AB and ABC)?
The reality is that most people who have a relationship that identifies as 'we', rather than two individuals sharing SOME aspects of their lives, are often co-dependent (you might go do some research on that if you don't recognise the term).
Bringing a third person into a co-dependent relationship is, trust me, not a recipe for long-term success.
