As time goes by, they can sometimes feel sick and tired of marriage because of many things such as relationship conflicts, parenting, financial concerns etc.
The married people may want to be released from all kinds of responsibility even for a short time.
I feel the same way. Actually, I'm not the one who crave to be free from marriage life but these days, From time to time, I see myself struggle with all surrouding me.
But on second thoughts, what allows me to stick to it in my everyday life, is a sense of responsiblity for my family.
I have my wife and son to love and protect. This commitment became my indentity and bring me happiness.
