Later he took my clothes, gold all my things and without informing he left me without informing. Later after 2 years I took divorce as he was ready to come for my son admission. Later while working my colleague was aware of all my life .. he said he wil accept my son and marry me. So he spoke to my parents and convinced and his mother was opposing this marriage due to my son but still he got married. He said he dint want kids but later he forced me for kid so I gave birth for my second son. Now he is hitting me and abusing with bad words not letting me to meet my first son has he dint let him to stay with us. He stay in my parents place. I don't know what to do. He don't have any interest on me.. every time he hits me use very bad words and blame me I spoiled his life .. please advise what should I do.
