We talked today about how he needed to show us he was attempting to find a full time job if he wants to keep living here. He agreed but then went back to his room and continued to play games all day.
That sounds familiar. Basically he blew you off. That's what Ben always did. "Yeah, ok. sure mom. I am trying. I am applying. No one is hiring." I knew they were hiring. I'm not sure what he was doing when he wasn't here. I would follow him to the gas stations, (not give him money) so that he has gas to go put in physical applications. I found out later his dad was giving him gas cards too, I sure he was using those for snacks and gas. just blowing them.
Good luck. I am glad it doesn't seem to be affecting the other kids. I wish I had advice or help for you. The only thing I can say is..MAKE sure anything he can steal and sell is locked up. don't leave any money or monetary value laying around. it will disappears and he will know nothing about it. He will try to make you think you are nuts that you left it there.
