Whilst at work yesterday it kicked off with dh and ds 16. Ds decided he wasn't going to do any school work which seems to be a daily things and was going to meet up with his gf and friends at 10am. Dh who's working at home obviously said no which escalated inti a row with dh locking the doors and ds trying to jump out the the bedroom window. Ds called dh a cunt and dh restrained or pinned him according to ds to stop him leaving. Ds then ended up smashing his laptopinto pieces, this is the second one now. First one broke which I think he actually dropped and now this one. He keeps saying he's going run away, wants to go into foster care etc. He doesn't respect dh or any of rules. Sick to death of the rows. Ds is not just meeting up with one person after checking his instagram so he's putting us all at risk. He doesn't help out around the house, do his school work or anything. Soon as he doesn't get his own way he walks out, threatens to kill himself or says he's going into care or smashes things up. I've had enough.
