I do not encourage couples to divorce, since a lasting marriage normally has it shares of pain, heartache, struggles and forgiveness and willingness to see it through. A great marriage is build in mutual understandings, friendship, respect and trust.
At some point, a person will realize whether the marriage is ever going to work or not. Each household has their own stories. I am brought up in a big family. Loving and affectionate families. There are nine of my father and his siblings. Five out of nine has a great marriage. One of them, try hard to work things. One hanged on bitterly and miserably. One had chose to end a long marriage with great relief.The youngest brother, a charming and good man, chose never to marry. He is in his mid forties and embracing life.
Sometimes we have to make the tough decision. It may work for others and may not work another. Just don't throw in the towel before you give it your all.
