exquisitetobe - I had problems getting my own ex off of the bills and such. For my hydro bill the required an email from her which I got by suggesting that she didn't want to be responsible for my spending. For my taxes and water bill they only changed that when her name was off the title. Similarly to the house insurance.
For satellite I'm not sure. A friend of mine actually lied to one of his providers saying that his ex was dead and that worked for him. Your mileage may vary
Other things were fortunately quite easy and a simple phone call or email did the trick.
It's too bad that you had that angry exchange with him. I can understand how frustrating it could be even though I've never had to deal with being blamed for anything. Yes, you are the bad person. The bad person who is holding everything together and providing a stable home and family for your children. The bad person who can be relied on. The bad person who is pretty darned upset at her ex and doesn't cover for his lies any more. The bad person that won't let her ex control her any more.
Good luck with getting the house ready to sell. I'm glad that's something I never had to do.
