C.,
I feel your frustration. My two boys are 5 & 7. They are addicted to violent video games that their dad plays. Our youngest was becoming a monster. I finally had to put my foot down. I told my husband what we were going to do and set rules. He had NO choice. All of our children's games went away, including their Nintendo DS's. Our oldest has had a difficult time with this since he used to play his DS on the school bus, which all of his friends do. I set our boys to 2 hrs of TV/Video games per day combined. Once the time is up, everything goes off and they have to find something else to do. It was difficult with our youngest and for me since he screamed, called me an ass hole and stupid mommy for days. Then all of a sudden, things changed. They don't like the time limit, but they have both become more respectful boys.
I know this will be difficult with an older child, but If you can get his dad on the band wagon, things may work out. While he is in your house, he should have to abide by your rules and show respect as far as TV/Game exposure. As far as the homework, he should be responsible for that himself. You shouldn't have to police him. If he's not doing it then that is his problem. He will have to endure the consequences of his actions.
I know you want to help, but sometimes you can't. Being a stepmom, there is only so much you can do because of boundaries. I feel that the games are the root cause of his agressiveness and other problems. His father needs to wake up, be a man and deal with his son. He needs to stop treating his son like an innocent child who says sorry and a big hug makes everything better. Your husband has a problem and needs help.
Get your husband help to get him out of denyal so that he can help his son.
Limit the TV/Games for a while and see if that helps. It is your home too, and you deserve peace of mind and safety.
Good luck.
