thatsss shit, i dunno what to sayy, sorry i dunno

i dont think there's anything you can do unless he's physically abusive.

you can try to get him to hit you...like really hit you. Than call the cops on him and have him taken away? But I do NOT suggest that

i know how u feel. My step-dad is the same way, he is very controling to my mom. He drinks every day from the time he wakes up til he goes to bed. And i do not like him. I have gotten into many fights with him. And alot of the time ive ran away because of the fights. And my mom comes up with some lame ass excuses on why he treats me like he does, like "hes been under alot of stress latley", or "he's just having a bad day" and he's like that all the time. He is really 2 faced. He shows everybody in my family this nice side to him. Then when him, me and my mom are home he becomes this completley different person. So i know how u feel. And theres really nothing u can do. But you could do what i did. I moved outta my moms and moved in with my gram & pap.

wait i'm confused at the start you said he was your step-dad and towards the end you refer to him as dad? hmm obviously your mum needs this guy in her life or loves him so much she'll forgive him, if he's a step-dad and you don't think you need him in you or your families lives you could always make up he hit or or tried to make a move on you, that's a bit dangerous and risky though it just depends on what you are willing to do to split this man and your mum up.

you could always like try talking to your mum again but really outline the facts, she might see more sense? or tell her you get scared by him and hate him, if he's been in your life practically all your life has he been like this for as long as you can remember or is it soemthing recent?

how about packing your stuff one day and leaving..go live with your real dad for a bit? and say you're not coming back until it's sorted, if she doesn't sort it out you know who she loves more, if she gets a divorce then it's savvy., you might not want to leaver your mum with your step dad but hopefully it won't be long before she sees sense

well then i think we've explored all the options what about other relatives close by? how about just saying out of the house as much as possible or not taling to him unles syou have to, just try not too see as much of him and leave your mum to it after all she's a grown up and should know what to do for the best

you could make a movie of yourself talking about how you feel and show some emotion, like crying. then give it to your mom or step dad.

Thats a very bad situation, i dont really think any advice that you get here will be able to help you, your probably going to have to talk to someone who is qualified to deal with the situation.
