When it comes to having a happy and healthy relationship, certain fundamentals must be there. These fundamentals are like the pillars of the foundation, and they are what holds everything together. The analogy that I've always used to describe what's important in a relationship is referring to a relationship as the cake. The cake is the foundation. The frosting is great, but without the cake, the frosting is just frosting. There won't be any substance without the cake. In other words, the cake is the foundation and it's essential to have, just like the fundamentals are in relationships. The frosting I compare to things like being wealthy, looking like a GQ or Victoria's Secret model, or even having certain common interests that aren't necessarily required to make the relationship work.
