Is happiness only for married couples?

absolutely not. everybody can be happy. why only married couples can have happiness ?

No I don't beleive happiness is only for married couples. Anyone can be happy. Not everyone has the same things that make them happy. Some people need to be married and totally committed to one person for the rest of their lives to be happy (that's me!!). Others are happy in the dating seen. Others are happy focusing on their careers. It's all up to the individual.
