"Annulment is a legal procedure for declaring a marriage null and void. Unlike divorce, it is usually retroactive, meaning that an annulled marriage is considered to be invalid from the beginning almost as if it had never taken place."
Marriage unites two people. The husband and wife are obliged to live together, observe mutual love, respect and support each other in good times or bad times. They shared love and made promises in front of God that is needed to fulfilled by the couple. That's why I am not agree in having an annulment because it only means that you forget everything that you promised to God and in front of everyone who believed in both of you. Annulment must avoid by a married couple because if you're still alive then there's still also a way to correct the mistakes that happened into your life. Once you decided to live with someone forever then make it true.
Annulment can't make your life better because it is just a reason to walk away from the problem you have.
