Hi people . I wanted to know is it OK to marry a girl at the age of 18 and I am 29 this is a arrange marriage . The only problem I am facing is getting myself to terms to having to marry a girl who is 11 years younger to me.. please help

At least here in China, that is a common age difference, I am over 11 years older than my wife and it is great, no problems at all because of age.

why is it a problem for you, age is the least of the issues, what she likes, thinks, values,
on arranged marriage, can she cook and clean house I guess, does she match up to the correct social status and economic status of your family
