me and my wife have misunderstanding my wife...

Give your self a time without contacting your wife or her family and then try to reach her again and talk to her and clarify the whole misunderstanding. As there are some problems that need a time of rest for you and her, and your continuous attempts to reach them exhaust you, so do not contact her through her family as long as they hide the truth from her. It is possible to seek the help of one of her close friends in order you could talk to her outside the house, not in her family's house, since that is way better.
