Sir Ive been married and living with my mil and husband for past 5 years. I have a 3 year old son. Because of my husband's toxic family I have developed lots of anxiety and have lost my peace of mind. My husband has 2 brothers who are not ready to take any responsibility of mil. They frequently visit with their family uninformed and mistreat me. My mil mentally tortures me and controls me. I have no personal space with my husband or my son. I have faced lots of atrocities due to which have fallen sick many a times. My husband has been suffering from sexual issues due to which we cant share any intimacy which already adds to stress in my marriage. My mil keeps interfering in all matters and mistreats me when husband goes to work. I have worked with reputed company's and after delivery have been working from home but can't concentrate. I want to live seperately with my husband and son but husband is not ready to leave mil. What are my options. I'm tired.
