K.-
I'm sorry for you & the kids. First of all, you and hubby need to have a heart to heart. He is being totally selfish. Some men need to know that their life does not 'end' at 5 with their job, it 'begins' at 5 when they come home. Tuning out in TV land is not a life. Of course he's tired, I'm sure his job is tough, but that is not an excuse to neglect his family for a fantasy land like TV.
Now, the dangerous part. My previous neighbor let their son watch whatever he wanted. They had on any show and he'd be running around. I tried to gently tell them that these shows were damaging, but 'Jaws' was his favorite movie at age 4. Give me a break. The kid had a TV with cable in his room since he was little. He is now a hard to handle, aggressive 12 year old boy and they just can't understand how this happened. Kids need boundaries in this area. They need a dad who is willing to put himself in their lives, not just when it's convenient. It is never convenient. Your husband is missing out terribly and if he wants to ruin his relationship with the boy and you, he is well on his way. By the way, good for you to take the child out of the situation and be sensitive to it.
I may sound harsh, but since I've watched these things occur it is imperative that these lessons be taken to heart. Perhaps you have someone in your life your husband respects enough to talk to? A good friend, pastor, his father (or therein may be the roots to this problem), your father or just some man who can help him see what he's missing. TV is fantasy, he may be addicted, getting him into reality will be a challenge, and just like any addiction he has to first see there is a problem.
Be loving toward him, but I do believe getting him to sit and talk to you and be honest (no screaming or crying), but tell him how you feel, that this is damaging your relationship and you really want his help to fix this. Men want to be a part of the solution, ask him to help take control of his family again and not just escape. When he escapes to fantasy land (TV) tell him you feel like he doesn't want to be in the real world with his real family and it hurts.
I don't know if this will help. I truly hope it helps someone. I just keep thinking of that little boy I used to know turning into someone violent and hateful, the warning signs were there, but they chose to ignore them.
Good luck
