Do your parents ever say things to you they shouldn't?

Last night i was talking to my step mom when my dad txted me. He had had my step mom check my msgs online and they saw that i was on the phone after nine, which shouldnt matter since it's summer and their rules dont apply at my mom's and it was also with my older sister because she was freaking out about her car not working when she needed to work the night shift. Also, i had told my one of my friends that i wanna move in with mom, just like i told him, and he got mad so out of no where he txted this to me:

I don't think you get it, slick, youre still under age and parental controls and i am sick of your shit. U DON"T HAVE A SAY OR A CHOICE! U try anything slick or pull anything to get back there then you'll 1. be in juvie 2. i will send your mom to jail 3. i will make damn sure you never see that retard brother of yours because i'll see to it that those visits end for good even if i have to claim him as a danger! Rules and laws still apply here and you are a minor which gives me full control of your life. So straighten your ass up before i straighten it out for you! And i swear to God i you try to move back in with your mom then you'll be sorry big time, i aint letting you go ANYWHERE!!!

I got that and i showed it to my mom and she freaked out. The main reason he's mad is because i want to move in with my mother to get away from him and he doesnt wanna lose my check. He called my mom and started yelling at her and so i called my step mom and was like "what did i do? i have done nothing but try to prove myself to that psycho path but i'm never good enough and he over reacts and jumps to conclusions! THIS is y i'm leaving!"

She went and started telling dad to calm down and the crazy man cusse her out! Then he got my mother angry with me and everyone was yelling but my step mom. I NEVER thought i'd see the day when my step mother defended me! But she was the only one listening to me which is really freaking strange and she was telling dad that half the crap he was saying wasnt true.

Then he took the phone from her and threatened me with juvy again and i told him he couldnt send me to juvy because i hadnt broken any laws and neither had mom and and that come December i would be out of the house because i was sick of all of the stuff he caused and the court system wouldnt let him keep me after they listen to all the threatening phone calls and read the msgs where he threatened to back hand me and then he yelled at me and said i was in a ton of trouble when i got home and i was gonna get "punished" for "back talking" in other word i'm gonna get back handed for wanting to move out. Then he hung up on me

My step mom txted me and apologized for him and then she made him txt and apologize to me but it's too late to change what he said. We recorded the whole conversation and he was calling me a bitch and threatening me and threatening my mother and acting like a 2yr old that didnt get his way. When the courts hear this there is no way they'll rule in his favor.
