At 13, she is incapable of handling a husband the responsibilities of a household, child bearing and rearing. I know many 13 year olds, I recall my own teen / pre-teen years I was well read emotionally mature for my age and yet I could not handle being married.
I can't imagine what man in his right mind would want to marry a 13 year old.
As a parent myself I feel for her mom and dad, they've lost five years with their daughter.
Misguided or coerced it doesn't matter - we should all know better, and make the right choice for the thirteen year old.
