Really struggling parenting my nearly 13 year old DS. He is in First year of High School having moved to an out of catchment secondary (Scotland) to try to give him a fresh start. He has two much older siblings but lives the life of an only child due to siblings being away at Uni and work. He is incredibly stubborn and struggles to control his anger. He shouts and storms off even when he knows that there will be firm but fair consequences. He is unable to change the path even though his Dad and I give him ways of doing so. He tends to try to deflect advice back to the giver. E.g at the moment trying to get him to do some school work, he will just say well you aren't doing anything either even though I have been doing work for my class (teacher). He struggles to accept blame and is very unmotivated to improve his skills - sports, music as soon as others who do put the effort in, improve more quickly than him. He will never apologise and seems unable to reflect that his reaction was unreasonable. We encourage our son and have tried over the years to allow him to find things he would like to do but he loses interest after the first few weeks. His last primary school teacher told us he was untrustworthy, manipulative and and had no friends due to his superior attitude and unpleasant behaviour towards his peers. We have two older children who are pleasant, kind and well balanced children. Our DS has been given the same opportunities and family values. My DH is the kindest, most reasonable man going and our DS seems to have none of these qualities. I am more reactive. I'm at a real loss and have really come to a dead end in being able to deal with this and help our son develop into a kind, empathetic man. Any suggestions?
