Hopefully that agency will help him find a job that he can enjoy. Maybe working will help him mature more and understand how to become more responsible. I'm sure it's hard for him to bounce back and forth from your house for two weeks to his dad's house for two weeks. But you're his mother and you need his help and his respect. Maybe you can sit him down and have a serious talk with him and explain how it makes you feel when he mistreats you?
