Mental and emotional abuse

I was a divorcee i have a son..... In 2015 i was working in one office... Where a man persuaded me for marriage 6 months.... He was like a angel with my son... Like a father.... He 1st told me he was unmarried... N i am his first love.... Then one day he took me to him parents n told me not to tell i was divorced or had son... But i knew its wrong n on the first meeting told them the truth.... They both got mad at me n verbally abused me... N removed me out of their home..... I told him sorry i cant do this as your parents not ready..... So after few days at night 2:30 i get a call from his frnds tell me he is committing suicide on railway tracks... They say because of you he fought his parents... Told them if i don't get her as wife i am killing my self...... So his friends tell me please please save his life... So that night he comes to my house were me my sister n my son age 3 that time are living....... From that day her never did go back..... We married but his parents never ever accepted me or my son but later after marriage i came to know i am his second wife... She had left him coz for dowry n abuse from inlaws and also eon 10 lakhs...... But It was to late now... But he never had any children with me... Nor has he adopted my son I legally its been 7 years now.... 5 times his parents n we came together as family but each time it was terrible torture for me n my son..... But now as covid began they cried n begged him to stay together... They love him so much he is there only son....... I have no parents both have died........ But every day is hell for me n my son no proper food.... Taunts all day...... My son is not allowed to come out of bedroom...... They call him mad..... He is 10 years old.... He playn dance n home... They tell my husband he is throwing things at us... Beatin us..... All false n horrible things about us...... I got thyroid hormonal imbalance high bp.... Menopause due to all this tensions..... Now i am 39.he has lost any connection with me.... He come home abuse me... Treats my son like dirt n continue his family life with them....... We are like dead bodies..... Cant talk cant laugh... Cant ask nothing...... I want to commit suicide n take my son with me.
