Harassment by wife and insulting daily

Married in 2014 in India - and left to USA as doing job there first one year things went little bit disturbance but after getting baby then starts fighting for silly things with me and my parents. Then consulted with prominent people and mediation done in India and moved to USA after one month again started fighting for unnecessary things and without reason. Meanwhile my parents came to USA then started a big show and she called to Police - and police came and took her to hospital and treated her. From that day on words she is emotionally black mailing me if I ask her to do any work she immediately reacts and saying "you know very well that what will I do - I will call Police" like this for every issue even if I did'nt lift phone in office due to office meeting or office work again again she will call and shouting over phone you come to home I will create a big show and call the police. I am fed up all these warning and black mailings - till now bared because of the child but now I am exhausted and want break up the marriage please help me and advise me .
