Some Dominicans who immigrate to places like Canada and the USA have a bigtime struggle with culture shock.....the cold, gloomy weather, being isolated from friends and relatives, frustration with the language, frustration with the new diet, being dependant upon someone else for some of the smallest of tasks. Not having the money that they expected to have.....All of this causes depression that no one can feel except him.
Not everyone has the psychological makeup to successfully deal with these negatives. He's going to need all of the love and understanding and patience that you can muster up. The bottom line is that you are going to have to decide if he and your marriage are worth it. I would bet that they are.
This is an excellent post but if you go back to the first post of this thread you'll see that he hasn't arrived in Canada yet.
