Hi
I too have a troubled step son. But is not as bad as your SS in the ways of stealing, bullying and abusive.
He to is rude to his parents and brother. He can make the atmosphere in the house difficult. He is selfish at times too.
My SS plays off his parents I.e. if he doesn’t get something from his mother he gets it from his father vice versa.
He had a trouble relationship with his mother and refused to see her for over 2 years until recently. He also refused counselling unlike his brother who now has better relations with his mother.
Now at 15 and in the last year of school is failing his exams. Seems more interested in friends and having fun.
My husband has been soft on him as a young child and has spoilt him more than the eldest. But now he is much firmer in disciplining him.
I really think you both have to disciple your step son more!
of course he should not be driving your car at all! He has no respect for you, the car or the law. Once he learns … he may take your car all the time and risk getting into an accident.
Are you both giving him money? How is he getting around places and doing stuff? I would stop giving any form of money/allowance.
He is in a transitional position.. entering adulthood, wanting to enjoy adult freedom but without taking responsibility or caring.
Im concerned about his behaviour towards women especially his sister, gf, and you! You’re lucky it was not more of a serious incident with the gf mother.
I think you and your husband need to sit down together and discuss the behaviour and consequences. You have to stop giving money and stop the driving until his behaviour improves. What happens if he continues? Once he is 18 years old what will he do? Will he leave home at 18? There definitely needs more action to his poor behaviour, it’s not fair on this sister to experience this level of abuse at home.
