if you have gotten no response from protective services..GO TO THE POLICE.

forget about your sense of manhood...is that less important than the safety of these children? your son? they are living with someone who you describe as dangerous? THEY ARE AT RISK. TO THROW UP YOUR HANDS & SAY "OH WELL I AM WHIPPED" IS HELPING WITH THE ABUSE.

go to the bank tell them a minor is controlling the account & close it. period. you are an adult.

i figure you can go to the authorities & risk losing your child because she flees & they hunt her down or you can do nothing & leave your child in a hellish situation while you watch.

DO SOMETHING. NOW.
