I'm a mum of 3 and step mum to 2. My OH and I live with my 3 children and see my OH children during most school holidays as they live quite far away. Up until recently our family dynamic has always been pretty good. However my middle son (11) has had a drastic change in his behaviour. Since starting comprehensive school he has become very disrespectful towards both my OH and myself and also been involved in instances of bullying (something I do not tolerate). He has been disciplined, grounded, no tech etc. He's generally a helpful kid but often he is very easily lead into making bad decisions. My problem now is my OH thinks he is beyond salvation and during some heated arguments he has used derogatory words to describe my son. I am under no illusion that my son is an angel but I also can't believe that there is no hope. My OH has been in their lives since he was 7 and has always been scared that one day one of them would turn around and say to him that he's not their father he doesn't get a say, this happened this week. My OH is ready to walk and I feel completely torn, I don't want to lose him or my step children but I can not give up on my son. Any advice greatly appreciated.
