Don't forget that you have come half way around the world to a different culture/way of life/way of thinking and behaving.
You have left behind the security and closeness of your family and your friends. You find yourself alone from everything you've ever known with no one to share or confide to, no one you can really express yourself to in your own language.
Being homesick comprises all these and more.
These issues in themselves will cause problems within yourself and within your relationship. It seems to me your husband may not really understand how you could be affected and so any realtionship issues may get magnified.
Somehow, you must talk with him about the way you feel. Try to get him to understand.
It may be difficult for him if he is really immature and has never experienced a life of independence. But without his understanding and support things will become more difficult to manage.
