Divorce

I am not happy with my married life want to get out of it. I got married last year on 3rd april under special marriage act. My wife was a divorcee with a 5 years old boy. After our marriage she satyed at het mothers place due to some exam of the child. She came to my place in the month of august. After couple of weeks family issues started. She want to do everything in her way doesn't want to follow the instructions of my mother regarding daily household works. There were issues with me also she doesnot want me to be with friends or colleagues. Life was going on with adjustments from my end only. As planned she went to mothers placed in november due to exams again & was supposed to come back in December. When time came i called her several times to arrange her return she dropped the plan by giving excuses. She said she doesn't want to live with my mother as she feels suffocated( as can't do whatever she want). I had tried sveral times to convince her but she was adament. She abused me on phone which she had done earlier also.finally as i was questioned everyday by my family in the month of February arounf 16th i went to her place to bring her back without informing her. She was very adament to not come with me. After several attempts when i realised she does not want to come next day i cam out of her place around 12.40 n went to station as our train was scheduled at 17.35. Then i got few calks form her neighbour n her cousin brother who told me that she realised everything n will go with me. I was happy n went back to take her. We cam back to kolkata next day n life was ok. I told my mother also to not speak with her much. Few days later again she same thing started. She was getting unknown calls on a daily basis being her husband i asked her to get the number changed which she denied. Daily quarrel started again n she went to her place on 14th of march. After. 10-12 days she called me n said she is pregnant as missed her periods. I denied her pregnancy as i took every possible precautions as i cannot think about another baby considering my financial conditions. She was stil not ready to come n asked me to go which i denied also. She then said she doesn't want the baby as well i told her to take medicine for that. Suddenly after few she called me n said she want to keep the baby informed my family n her mother also.my fsmily said that we need to think about this as so many things happened already. Also said that why did she left my house as she claimed she felt this when she was here. To cut the long story short i want to know how cant i get out of this marriage without mking any financial settlement. She is more qualified than me she has her own house. I have nothing apart from a monthly salary of 15k. She is with me at the moment n we both decided not to have the baby. Please advice as my lifr is becoming hell.
