Feeling miserable in an arranged marriage
I have been married for over 5 years. It was an arranged marriage and throughout my existence in the past 5 years, there have been very few moments when I have felt truly happy. My wife has always lived in a nuclear family and seldom respects my parents. While I have always been a sensitive, sophisticated guy, she continues to be a loudmouth, arrogant person, who wants things to be done only her way. Her parents have always been supportive of her behaviour and have even allowed her to stay at their place for over a year after one of her bitter fights with me and my family. I aspire to live with my parents and have found little support from her and her family as far as my vision and dreams for the life ahead. Her parents, fearing social backlash, for keeping her far too long at their home somehow convinced her to move back with me at our home but her behaviour has hardly been cordial. That was my brief background, now here are my two dilemmas:
A) We now have a daughter and my parents have guided me to just follow her instructions and try to keep her happy by doing whatever she wants. But it suffocates me because often her demands are unjustified.
B) Her elder sister tries to unnecessarily interfere with our life and calls her every day to check out the latest gossip in our life. Her elder sister even abused me and spoke about my family in a derogatory way on phone while my wife was staying with her parents for a year. I now insist on keeping her sister out of our lives, but my wife behaves arrogantly and wants her sister to be allowed to continue her relationship with me as my sister-in-law, while I don't think I can tolerate her anymore in my life.
I sometimes feel like committing suicide to get rid of the problems in my life, but refrain from doing it only for the sake of my parents who love me a lot. I don't know what should my approach be moving forward?
