I dont think I can, I can't seem to find anyway forward, every night is a battle as he kicks off night after night. We have tried everything such as boundaries. Ignoring does not work as he can get violent. I can't sit back and watch him destroy my 3 daughters self confidence through his attitude and abuse and watch them tread on eggshells to stop him exploding
I have been told to create a safe space for me and then but when he DOJlows us around the house hurling abuse and accusing us of doing x y z and misinterpreting situations because he takes things very literally.
He doesn't believe anything you tell him, if it doesn't happen in his realm then it didn't happen, eg he lost his temper when I told him that his dad was unable to get his car fixed until tomorrow and his response was dads a lying little twonk because he told me it would be done today. Oh your a liar mum then too cos its probably your fault his car broke down 
another one seems to be come on ds off the Xbox now. Cue tantrum and the most bizzarre comment. Why why oh so u want the Xbox now do you so you can sell it to back to hmv. Then will not listen to any sort of reason at all and promptly starts packing it up and yelling and throwing things.
Honestly he comes out constantly with these bizzarre and illogical statements and he truly believes what he is saying. I lost it tonight and shouted some stuff back which I know I shouldnt have done but he made dd1 c ry by calling her a useless cow who was thick as shit.
he does have ADHD and is currently waiting for asd assessment but hes 12 and surely he should be more self aware.
