I am separated for two times, I tried but i guess I am unfit for marriage life. Marriage is a trial and error, if its error why stay. If the marriage turned to be unhappy, why not find a way out. I pity women who stay married and pretend to be happy but trapped in an unhappy marriage. Life is supposed to be fun. Staying in an unhappy marriage is like committing a crime against yourself. If setting someone free makes your partner happy, then do it. It would be unfair on your part to be be with someone who is with you just because he/ she does n't have a choice.
