Cannot leave with wife and cannot leave without kids?

2nd marriage for both of us, my wife wants to have one way relationship where she can point fingers at my family 24 X 7 rather then improving her life, eg: understanding, learning and communicating in English. Her job is to torture mentally 24 hrs/day. Knowing she will get custody she did not hesitate and did tried to hit me with broom when we had argument, she can find faults all the time but when I do she goes through roof. she can talk about our problem at her in my absence which I don’t like it but will accept her attitude but when i talk on phone about our problem she did not liked and told me to talk in her presence which i ignored and she locked me out of the house and had to enter through breaking the window at around 11 pm. she lies, manipulates the facts and gain full support of her two sisters and mother and now they behave like they are supporting me 100% financially. She knows court will give her custody of 2 kids what can I do ??
