The mere mention of the word "Divorce" is a bane for any marriage.
It is really tough on either or both partners to know that the relation they nurtured for whatever time will now get destroyed.
If it is just one partner who is keen on the separation, it is obvious that the other rational partner would try to convince the other through discussion.
If that does not work then she would talk with the friends and family of the person to see if they can sway him.
If either do not work, it just seems as if that is the end of the world.
Marriage as a concept and institution is important, not just for the two individuals but also for the entire society.
So any divorce is really not good for general social being.
Of course at a personal level it would mean loneliness with memories of the person who is now going around with someone else.
So you really need to try your best to save it.
Give it your everything as the results are just amazing.
A great way to do that is to create the aura and mystery around you.
Give him his space and ensure that you get yours too.
At that same time you also need to kind of neglect him once in a while.
The idea is that you do not ignore him completely but do not be in front off him all the time.
As soon as you move slightly away from him, it will trigger his curiosity and that will mean he would want to spend those moments with you again.
Before marriage you were that kind of person which attracted him to you.
If you can recreate the same feeling you would have got his interest.
After that it will be just you in his mind and no place for divorce.
