Teenager out of control and violent

Hes off again. Twice in two weeks.

Last night we found Coke all over the wall in the room where his PC is. We've got past experience with this sort of thing - hes lost his temper while playing computer games and broken things. Also, hes got a habit of something breaking (even if its an accident) and then just leaving it and not bothering to tell anyone.

Anyway, so we're 99.99% sure hes done this. So wife has a calm word with him and asked him whats going on here. In about 3 seconds literally hes gone from 0 to 100. Hes up in his mothers face (2nd time in a week now), being really aggressive and swears blind that no-one ever believes him and hes got no idea how the Coke got up the wall.

The things worrying us right now are:-

1) His aggression. He seems to think if he disagrees with someone he can get up in their face and escalate things. Let alone the fact that this is his mother we're talking about here.

2) He seems to think that hes not wrong. I've literally heard "I didn't do it and you always accuse me of lying" about 50 times. EVERY SINGLE TIME so far hes been found out. One time he is going to be telling the truth I know but still his average isn't good.

What do we do?

We've removed his PC privileges AGAIN. Mainly due to the unacceptable aggressive behaviour. In all honesty, if he'd admitted he'd done it straight away he would have been give a task to clean the wall, and a warning about his behaviour.

I honestly don't know how hes going to cope in the real world as an adult.

IDK what age they're considered sufficiently adult now, but maybe you might consider telling him "currently you're age X and so we are unfortunately responsible for your actions, but when you reach age Y you're considered an adult and responsible for your own actions.  If you carry on as you are, then as soon as you are age Y and we are no longer responsible then I'm afraid you're going to have to move out and take responsibility for yourself because we are no longer willing to put up with your anti-social behaviour son.

It sounds like you're stuck in a situation with no good choices :-(.  If he's too whatever it is to listen to good sense, and you've accepted that it's reached the stage where he's a clear and present danger to people in the house, then it seems he has to go...  I'm not sure what the options are, it's not my area, but I guess maybe speaking to the Police might be a good first step to see if they can point you in the possible directions.  I'm sure they unfortunately have to deal with more than their share of domestic abuse situations...

We;ve given him warning after warning. Not nastily but pointing out what could well happen if it continues. He assaulted me a few months ago.

A week ago he got in his mothers face and screamed "go on then lets go". He got warned what would happen if it continued. He got in my face the other day when the punishment was announced - just a PC ban until he'd cleaned up the wall. I ignored but AGAIN told him the deal.

Day later hes come home, decided he wasnt going to be banned. Mother turned PC off so hes shoved her flying.

We've honestly tried it all. He just will not listen or understand that there are serious consequences.

Its got the point now where hes a danger to other people in the house. As you say, if he was old enough he'd be gone by now.
