Quoting Isaac's mommy :" <blockquote><b>Quoting amor♥:</b>" When he leaves for work (or anywhere else) ... [snip!] ... That's what I thought about, but he's made so many threats towards me. And I guess I just feel bad for possibly hurting him."
If he doesnt know where you are, he would have to find you to follow through with threats. Call the police and get a restraining order once you leave. Then contact them if he makes contact with you
As for hurting him, smurf him. He is abusing you, he doesnt care about you.
