I am a SD to 2 kids and have my own 3, two teens and a 4yo. For the last 18 months + SS has been having issues with boundaries. Started with things like accessing porn, inappropriate messaging, inappropriate behaviour towards SD and has now turned to vaping, grades dropping, attitude stinks, using OTC medicines secretively, NOS use and god knows what else. Recently myself and my family were attacked by a gang of lads who he had got himself into trouble with, my 4yo was screamed at, my children told they were lucky they weren't killed, a truly awful terrifying experience. SS shows zero remorse, zero interest in changing his behaviour, accepts no responsiblity for the mistakes he is making and is totally disengaged with life. I am at a loss as to what to do. I have now found gas sniffing paraphernalia in his bedroom and have hit the roof. I don't know what to do or how many chances I can give him. If he was sorry I might have more patience but he genuinely does not seem to care and only becomes angry if pressed about it. I don't know how much longer I can be in this situation, I don't trust him, don't feel my children are safe around him. I don't know what to do. DH and BM want to 'support' him through these challenges which I can understand, but this isn't just about him, there are other children who live here and he clearly doesn't care about them or the affect his behaviour is having on them. I've said Ito DH that I don't want him here unless he can show he is sorry and wants to change, DH has refused to let that happen. I don't now what to do anymore. Any advice much appreciated!
