Family not setup

Hi , I got married 6 months back and I have not set up family with my wife till now. First 2 months I went on project to US and returned back and brought her some gifts. After that there was 20 days gap because of aashada masam and family set up was not possible. In this mean time she started harassing my character, abusing personal life, and said she will treat me like a customer if I get close to her. I met her family and told them about how she abused me. They agreed that it’s her mistake and asked me to give her a chance. I asked them to take hm their daughter and teach her how to talk and what to talk and all and get her to me with a guarantee letter saying that she will not talk like that in future. They took their daughter back home and never came back, nor wrote that letter. Recently her father called me over phone and abused me, my mother with cheap words and warned me that he will kill me and he will beat me up and he will make me loose my job and will kill my family. With that call I am decided not to continue this relationship with family who talks like this. We have not consummated till now in this marriage. If I go for divorce, how strong my case is and what level of percentage I can protect my job and family. Because my job is the only source of income to my family and no other earnings from anyone, that’s why they are targeting my job and family.
