Im a tad confused .. Did you not realize you and her didnt have a lot in common before you married her? Can you help her learn English or pay for classes maybe?

Your kind of in a bit of a mess...

She now carries your child... Shes in another country and cant speak the language.. So you divorce her? What does she do then ? Stay there ? Move back to Africa? You will have a child to support and be part of the child's life ?

Does your wife even know your unhappy ? Maybe marriage counseling could benefit you.
