I think you have totally done the right thing. You cannot keep bailing him out he knows that bank of mum and dad will end up paying eventually even though you are doing it under severe duress.
The thought of our sons being beaten up is horrific but maybe it wld put them at rock bottom that they decide to really crack their habit.
Everyone I spoke to wld tell me me helping him is enabling him. I mean I’m still in our hideous addiction journey with my son but have decided I am not going to pay for his addiction. It will be never ending. Its horrendous that we feel nothing but love for our kids who only see us as walking cash machines. I really feel for you. Addiction is mental torture as much for us as living parents as it is for them. I hope you manage to relax and sleep tonight xxx
