Criminal activity but not appearing in divorce case hearing

I have few cases against my husband and it’s been two years divorce case is going on but he never come to attend the hearing. Judge made him as a ex partie but from the past two months his brother and relatives are chasing and threatening me. Today again the same thing happened with me , when I was going to bank for my dad work . He saw me on the way and he started threatening me and told me that I should take back the case otherwise we will kill you /burn you. It’s very scary experience. I went to police station and written complaint against him. But I know they will not do anything thing against my complaint. Today I come to know my IO also has been changed but police officers didn’t give any information about him. Now it becomes serious. What should I do? How will I get relief from him and alimony too. Since I am a patient also. I got anxiety attacks frequently and then I failed to do anything in such situations.
