Try to meet your wife alone! take her out to some cool place, spend with her from morning to evening, speak to her with love, never try explain your feeling, just you try to understand her objective, feelings.
Stop talking to her parents, you should realize that this kind of women never understand men feeling, so its a just waste of energy if you start briefing your feelings, future plans.
Face to face discussion always help us to understand if other person telling truth or not, we don't get solution over phone calls.. phone calls always create only aruguments.
If possible try take video conversation during your meetings.
Try to save your marriage with meeting her regularly, if possible show your love with romance, end of the day if you both divorced.. you will have a feeling you did all best efforts to save your marriage, love, promise, but she did not deserver your love.
