They just shared an understanding about what a relationship means. They also both have experience working in brothels. Indiscretions are a matter of when rather than if, and usually sooner rather than later. They were not naive enough to believe that they can meet 100% of each other's needs, so they subcontract the 5% or 10% or whatever % out and it never mattered as long as they came home to each other at the end of the day.

If it was not Raylan in question, but anyone else, who never asks and makes you feel replaced, would you do this to yourself, and take whatever leftovers that get cast your way, and continue to want to stay?

The only person who's going to look after you and chase after what you want is yourself."
