I wonder how many posters have experience of aggressive teenagers?
Me
Seeyounearerthetime there's always a reason. You're answering 'I wasn't provoked' in terms of at the exact time of your violent behaviour. What about the years preceding? Are you still behaving like that? If not why not? Reasons can include mental or physical illness, abuse (not necessarily by the person you're being violent to) etc but there will be a reason.
Also the way the dh is behaving is not discipline (and I'm a believer in discipline), it's controlling, provoking, aggressive and abusive.
"I can see your DS coming to you in a few years time telling you he never felt supported..." If he goes to the OP at all. If things get much worse and OP continues to stay with her partner I can see the son cutting her off altogether!
"If so I'd like other posters to suggest how this situation is handled?" Yes it is abusive and aggressive behaviour from the stepfather. If it weren't (and I believe the op is not telling the whole story due perhaps to embarrassment) ss would not be involved, child would not be cin and CPP would certainly not be being mooted as a possible soon to be taken next step. The stepfather should be being an adult! Ie not getting aggressive and abusive every time, not holding the son solely responsible (who is still a child and as a pp has noted was very much a child when this started when he was only 14), staying much calmer and while it's acceptable to point out the behaviour is unacceptable at 16, even 14, the boy can be spoken to about any unacceptable behaviour at a later point when everyone's calmed down.
Actually with the OP stating that the stepfather is blocking the son from going elsewhere it sounds like the son is more mature and is trying to remove himself from a heated situation (trying to escape violent abuse even), and the stepfather is preventing that inflaming a situation that's already volatile!
"You don't snatch something or aggressively block a teenager's exit from an argument and then get to play the victim, I'm afraid." Spot on!
The dh is unwilling to address his anger issues from a perspective of taking responsibility for HIS unacceptable behaviour this will happen with the younger dc too when they're teens.
"He has the opinion that it's his way or the highway" then he has to go! If you don't get rid you are not a loving mother. Harsh but true.
A family therapist will not work in this situation as the dh is unwilling to accept responsibility for his actions.
I agree that the OP is probably being controlled/ea too if not physically and needs help to remove this man from her life BUT it still needs to be done.
