Mutual divorce & falls complaint case on my wife.

Dear Sir/Madam, My name is XXXXXX,I have completed my B.Com in 2004 from Kurnool District, Andhra Pradesh, where we got arranged marriage with both side family elders blessings at my home in Aug’2010 (we suppose to got married on Jun’2010, but my father-in-law has met with accident and postponed to Aug’2010). Before, my marriage onward's I have been leaving at Hyderabad since Jun’2006. after my marriage we both are leaving alone at Hyderabad from the beginning to till she left from my home (Some time my Mother-in-law was stayed with us to take care of my Son dieting). I am very less earner employee in a private company. After 2 months of marriage, she started to quarreling with the neighbors, later with house owners. Whenever, she quarrels with house owners, they will say that please vacate home or else will throughout your households as your wife is abusing on us otherwise will complete on your wife under nonsense case. In this case I don’t have any options to do anymore or to favor to my wife. Even though I have supported her to gain the good attitude with others and given good precaution her to change her mind set as I have observed in my wife behavior and found she having some “Incurable Psychologically/Mental Disorder” as she will behave and talk like child. Same I have been informed to my in-law’s but they have not taken care of my words. reversely they have used abuse words on me & warned me, if you say like this will complaint at police against you as your harassing & asking extra dowry, I thought they are fooling me. Within 6years of my marriage life I have changed 8 house’s, because of my wife attitude & abuse talking with others. she has behave, talk, quarrel like same way with her mother & my parents also. If I ask her why your behaving like this means, immediately she will attempt for suicide by herself like this 4 times attempted, whenever she done like this, each time I have suffered lot. Finally I have resigned to privet job and shitted my house holds to my own house (which was was located in a small village) because it’s own house. After that one fine evening she left the house with her belonging to leave my 2year Child at my home. Same day evening around 7pm I got call from the Police station your wife has given a complete against on you. The next day we went to police and handover my child to my wife in front of Police officers. I told them about my wife attitude and behaviour, they also suggested consult a Psychiatrist. But my wife and my family members are not supported for treatment even i have bee ready to bare that medical expenses. Again, they went to police station to saying that he is not coming to bring her to his home, I shocked to hear that. Later we went to Village "Panchayat" head and they suggested to my wife parents to put her in separate house instated of keeping in your house, why because your are not accepting to send her with her husband to stay at his village house. But they have not seen any house or she didn’t allowing to talk with my kids also always I have to talk with her only. She never mingled with my family and she also earlier so many times repeatedly using the words like I don’t want you, I don’t your "Mangalsutra" i will remove it and give you or else marry me with other groom, because don’t like to marry you and my parents also not agreed to marry with you (except my father). But I have not scared about the word, because her mother and relatives wherever they talk with me, that time they will explain my wife childish behavior & attitude as saying that, she doesn’t know the society, culture, way of talking with others so you have to adjust with her. Now they went to her brother house and they have complained on me at non-circle police station (which is very far to my village) under 498(A). but we never harassed & forced for dowry. Her brother is warring me saying that will kill you and remover your heards or I will come along with my members and will smash you and your family, will keep you in jail for long time by putting other cases on you. Please suggest me, in this situation what should I do.? Can I apply for mutual divorces & complaint on my wife brother under Criminal ground.!
