Well. To answer your query, the answer is very simple as to it is quite possible that you may just need to take a short break or you could also call it that you both might be needing space from one another. This is called a trial separation. Since, there are many couples who find that this helps them to gain a better perspective on their marriage.
It is certainly amazing what a little time a way can actually achieve. Thus, a trial separation will allow you to make more cultured decision and will help get rid of the after thoughts of What if I did this ? or What if we tried that?
Thus, after a divorce has taken place it is very common to have feelings of repentance or regret. These types of emotions usually are often overstated when the decision to divorce is made in a impulsive fashion. :(

Ya Sabrina I too agree with your view. There are many options in front of u. You can just simply leave apart from him without any legal notification but if u want to marry any another person then u have to take divorce from him.
And why are u avoiding divorce????????
