Name changed as this could be outing.
Son is 20. And is a single dad to a 11 month old boy. His mum isn't involved and wanted to put him up for adoption but son told her not to.
The problem is son goes out for a drink every night/every other night and takes drugs when he isn't drinking.
He's also said he is a terrible dad and DGS should've been adopted as he would have better parents.
What should I do?
