I want to leave

I want to divorce but am scared.

Scared because I’m a SAHM. He uses money to control me

scared because he has a criminal past and i don’t want him to have custody of our child.

Scared because he’s in a gang and promised to hurt me if I leave.

Scared because the police may not listen and would listen to his lies

I wish I knew how to leave... I feel like if something happens to me no one would know HE did it.... what to do....
