Is it okay to have an extramarital affair?

I do not believe in extramarital affairs. If you are married, you should not be romantically involved with no one but your spouse. This is one reason the divorce rate is so high. You should marry your soul mate and the love of your life and have a strong lasting marriage. An affair should never even be an option.

Not always people get to marry whom they love, circumstances many a times leads to a compromised matrimony. Later, one may connect better with a third person and find compatibilty and comfort outside their marriage. Would it be right to see such a situation in black and white? Wouldn't a shade of grey be an option as well?

You should make sure you are marrying the person you want to be with the rest of your life before marrying. Think about if there are children involved. They are the ones whom would suffer the most from their parents divorcing. That alone may lead to them having trouble with relationships.
