Can I ask does your son work?
When you say you wont put him out then I’m afraid to say you are enabling him.
Anything we do in life to help them including putting a roof over their head enables them to continue without the harsh consequences for example of losing their accommodation.
He probably knows that no matter how low he gets hes always got mum there and she wont kick me out so he always has a roof over his head and food in his tummy. That I’m afraid is not rock bottom.
I feel your pain but what consequences has he had to face when u say he has been at rock bottom?
Or is it that u feel its rock bottom but actually it isnt for him?
