Can I apply for nullity of marriage

I got married on 26/04/2024.. now it's 5 months After one month of my marriage I came to know about my husband's relationship with a lady for about three years . they were in live in relationship like husband and wife without getting married... When I asked about this with my husband again he lied to me like that lady is blackmailing me to be with her and misleading me to be with her my intention is not to cheat you I want to be live with you life long please give me one chance to prove myself. And my in-laws also locked me by emotional blackmail... Again I trusted them as before and gave second chance.. after that that lady filed case against my husband for betrayed her and her children (her first husband's children)... After one month of this incident my husband started to avoid me And I informed to my family about his relationship...soon after my husband and in-laws came to know about that I informed to my mother and brother and relatives they start to backfire and my husband told me I can't continue my life with you anymore as you spread to everyone about my relationship... And got settlement for 19 lakhs they have give me as compensation among family members...and they took two months time.. After one month they gave false complaint against me and family Now they are saying they can give only 8 lakh... Can I apply for nullity of marriage if so do I get compensation
