Want to git rid of my wife

It is my 2nd marriage, I married to a known girl from my relatives. Since it's my 2nd marriage my family thought I should marry this girl because she is from a poor lower-middle-class family. in fact, she has not done her schooling, got a fake certificate at the time of nikah nama. I didn't take dowry a single penny, I just expected furniture to be given to start our new life smoothly and this has been agreed by both families before marriage. I used to work in Kerala so after marriage, I went to Kerala leaving my wife at her parent's residence. In a month I got the news that my wife conceived, so I found a job in Hyderabad and returned back to Hyderabad to stay with her during pregnancy. Her mother scolded me like anything when I asked to give us furniture to start a new life in a rented house I have an audio proof for the same, then both families sat and discussed and finally a rupies 50K given to purchase the furniture. She has taken advantage of my 2nd marriage and started poking me in every aspect by letting me down. She is avoiding to attend family functions and marriages and also expecting me to do the same. She is mentally harassing me when I go to my native place to see my family members, not behaving well with my family members and not allowing them to stay a single day at my residency. In this frustration I don't know what I'm gonna do , getting thoughts of suicide. I have a baby girl I'm sure if my baby stays with her gets a bad impact and influence on my baby. I just want to take divorce and also I would like to take care of my baby. So kindly suggest and guide me as soon as possible because it's getting worse day by day. Its shame to motherhood "she avoided feeding her own milk" now we are feeding powder milk I don't know how come she became women. She is only having feelings on my money not on me, I can easily count the days on my fingers when I had 3times of home food made by her. Please suggest to me what to do, I would prefer to take a loan and give her compensation rather than living with her.
