No matter how much your wife tortures you, you should never abuse or fight with her. Be patient, talk to your family about this.
You can do these measures to see your family happy and to convince your wife. You have to tell everything openly so that you can get proper guidance.
Using alcohol or drugs in sorrow is the worst, due to which you'll move towards major mental & physical diseases. Addiction is not a permanent answer to numb sorrow.
To maintain the happiness & peace in your family and to convince your wife, consult a family counselor. Share every problem clearly so that a proper way can be found.
Make your in-laws aware of your pain, share your dilemma. Never misbehave with your in-laws regarding your wife.
It is necessary for you to take legal advice for justice. The way you have gone through bad treatment, it is your right that the law and order system should know about it.
There is no point in being in a relationship where your thinking is stifled, you are tortured everyday; you are abused everyday.
