Does anyone know why Rob Zombie puts Sherri Moon Zombie in everything he does?

I'm not complaining here. I am just genuinely curious. Why does he have to put Sherri Moon Zombie in everything he does? In all of his music videos, that was fine. However, he's even put her in every movie he has done. That's a little surprising, honestly. I mean, he's even written her a part in Halloween 2. If you remember correctly, she died in Halloween. It won't be just her voice in Michael Myers head, instead, she will be physically presented like a ghost or something. In the trailer she's even dressed like a deranged version of Michael Myers' mother, but in a ghostly fashion.

Here's the H2 trailer:

H2: Halloween 2 (2009) - Official Theatrical Trailer

Check out the trailer if you haven't seen it. You can see Sherri Moon Zombie with white hair and dressed in a gown, telling Michael Myers to kill for her, basically. A lot of people are complaining that Rob Zombie is copying Jason's mother from the Friday The 13th series. Just check it out for yourself and then let me know what you think.

Interview with Rob Zombie:

Halloween (2007) - Rob Zombie World Premiere Interview

Here he explains that he brings a lot of his friends in because he can trust them. I guess I can see his point with that, but what does he need to trust them with? Does he put his wife in everything because he trusts her more than anyone?

Another question, would he put her in a movie even if her character completely ruined the movie? I mean, it's obvious he specifically writes parts just for her. I'm curious to hear all opinions on this topic. I'm not insulting anyone or anything. As I said, I am just genuinely curious.
