No, nothing should be fake. It really is about making a better YOU. Being the "better option" can mean many things. It can mean you "know" you are a better person in general, the qualites you possess are valuable assets that anyone would want in a life partner, the history you have together, the children you have together, the memories or years that would be difficult to replicate in another relationship....
Just because you know you are a "better option" doesn't mean the spouse will believe this and stop a divorce. One can't always stop a divorce, but you may be able to learn from the situation, evolve, and have even better future relationships.
There is no arriving, ever. It is all a continual becoming.
