We don’t know why his mum couldn’t handle him at 11 or however old he was. However from my experience of my 16 yo dd’s friend’s parents, I see a lot of lack of resilience from the parents and incredibly shitty behaviour, that’s biological parents btw.
One mum is not talking to her 16 yo dd and blaming her dd for the demise of their marriage. This is so totally untrue and stems from something incredibly insignificant that the girl shouldn’t have been involved in but none of the adults have any boundaries. The mum has also blocked the girl and is refusing to do anything for her at all…not that she did much before. This girl doesn’t argue with her parents much at all, is being made to work in the family business full time and is too tired to study for the course she’s been enrolled on by her father. Mum (sahm with a housekeeper) cannot be bothered to cook the food her dd wants so at 16 she comes home from work and cooks for herself, this predates the current situation. She is a really good kid and how she doesn’t have serious mental health issues idk. Additionally she was made to go to work and apart from being allowed to go to the very small local town she had to stay at home the whole summer for an incredibly minor infraction, which the mum said her heart was broken over 🙄. That’s the summer post GCSE, which is supposed to be so much fun. She now is finally allowed out and on sleepovers again. Dad is a workaholic.
The second, her parents are nesting pending sale of the house and in the middle of a divorce. The mum threw her 16 yo dd out at the start of her week. Dad is staying with his new girlfriend on the weeks off (he’s moved on fast, no overlap btw) and she doesn’t have room in her house so she’s staying with a friend close to college. The girl has had recent issues with her mum and her mum slapped her about 6 months ago, which took a lot of repair work. I’m sure the girl is no angel. But she’s a good kid, studied for her GCSEs, is going to college, doing her work, helping out at home, holding down a part time job etc.
As for us, I am absolutely sure these parents would buckle with what we are facing with my dd, who has anorexia and I’ve fought tooth and nail to get her to where she is right now. A long way from being mentally well or healed but eating, gaining weight again very slowly atm. Most parents have no idea just how vile a mentally ill anorexic can be to their parents / caregivers when challenged and challenge I must as without intervention on the amount she was eating and drinking, she would have died.
As for the op. If this is what the boy has done and similar other incidents, they are minor infractions in the scheme of things. Yes, his dad needs to be clear this is totally unacceptable to treat his stepmum in this way. And explain to him how intimidating males can be to females. But to threaten to kick him out, that is just awful. If things like violence, intimidation or drugs are involved this would be a somewhat different situation and for both the dad and stepmum to decide on an action plan.
At 15/16 in my limited experience, boys are in the most part, if handled correctly, quite sweet and caring but in the wrong hands not. Dd’s male friends remind me of overgrown puppies waiting to grow into their bodies.
