Child Custody/Domestic Violence

Is The Father Allowed After Domestic Violence To Take Custody Of A Unborn Child From Having A Previous Domestic Violence Relationship With The Mother Introducing His Self As An Affiliated Gang Member Whom Claiming He Is Murdering People ???? Than From Previous Conversations Of Making Social Media Accounts , Whom I Was Being Harassed About My Pregnancy Forcefully Against My Will (Of Talking) & For My Own Child/Unborn Being Taking From My Arms. He Is Known For Substance Abuse & Smoking , Drugs & Family Violence .. Hangs With A Lot & Including Underage People Over The Internet. Has 2 Other Kids & Is Known For Powerful Comments & Followed By Actions Of Physical , Verbal , Emotional Etc Violence. He Likes To Claim Along With With His Other Biological Son Of Taking My Life. He Once Made Comments , He Wasn't Who He Say He Was & Then Lying About His Age & Other Forms Of Background. I Feel Like I Am Being Played By My Freedom Because I Am Always Being Called A Nigger , Ate Off Of & Harassed By These Strangers & Others Over The Internet .. What Should I Do ???? Thank You ..
