This place is supposed to be focused on saving your marriage, no matter how far gone it is.
No, this place is about fixing yourself first. That is the goal. Get yourself to a place where you can be the best you can, so if your ex does come back you will be in a better place for a new relationship. And if she doesn't, then you will be a better person for the next relationship with someone else.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
