if u are smart and can really tell that he wont kill someone then i would make a plan to hurt him or threaten to tell pople wat he did. KICK HIS f***IN ASS INTO THE f***IN DIRT TILL HES IN HELL. u should tell ur mom and have him arested even though its embarissing and degrading its better then not getting help. its just another human u can outsmart him, dont be scared of him. DONT LET HIM RUIN UR LIFE. GET EVIDENCE OR VIDEO OF HIM ABUSING U NAD THERES all the evidence right there this man deserves to never live. i feel for u dont let him bring u down ur better then him hes not bertter than u hope the best for ur life
