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....
Wow, that's great. I really needed to read that today...thanks.
