I got married in the year 2002, my wife is 14 years old then me, from that time my parents want me to leave her either taking divorce or.. and marry other girl.
I married her as our Rasul married her first wife as she is also older then our Rasul. Did I do wrong by following him.
As my parents want a child from me but as I told you she is older than me and she could not give birth.
And my financial condition is also not so good after marriage so now I am think what to do either change my name or change my religion.

If posible please answer me.

I'm so sorry, but I don't understand your question.

This much I do understand:

Your wife is 14 years older than you.
She is too old to have children.
Your parents were not happy with the marriage.

Could you please explain what 'Rasul' is and why you want to change your name or religion. What does this have to do with your marriage?
