Maintenance till mutual divorce

Hi , I am Punjabi Indian Girl married since 10 years to a Punjabi. I tried to adjust to their standard of living but there were differences throughout. The main reason is because I am educated and my husband's family is not and neither my husband. All are from my In-laws house are drunken and street gambler. From the very first day of my Marriage my in laws (Sister-in-Law's husband ) interfered in all my discussions which was a little disturbing for me even he has bad eye on me. and he told all of them that "She is mine no body told or say anything to her". Since I had married him with me family consent, after that I had no one to share my grievances. However initially my husband stood by my side but gradually he neglected things. there was two incident in which my husband also support my Sister-in-law's husband to attempt to rape me but my boldness save my dignity. Now that I have a 11 year old and still for small reasons my in laws and me fight a lot. My sis- in-law says that she has some issue with her husband because of me and her husband warned me that if I did not serve myself in front of him then he will surely rape me in-front of my both kids and no one will stop him because my sister-in-law and my husband also help him. I am scared and my husband is not on my side too. I think it is better to live separate. But what about my kid. they are small enough to forget what is happening now but if I adjust for few more years and then take a decision to separate then at that age he might get affected with all this. But last 8 months suddenly our paternal shops are going to sale till then they all want to divorce and take all benefits of property matters even they want to take hold on all money matter's. Please advice.
