My now EX husband.

So after the last ordeal, he went to jail, I got full custody of our kids. He’s seen them once for two hours in the last two months. He also has a new ex drug addict girlfriend, and is demanding to see our kids. Then he sends me this, am I the only one that has a problem with how he’s talking about our kids? He also admitted to killing our 8 week old puppy. What do you guys think? He says he’s going to take me back to court for custody of our kids. I really need some advice. I’m heartbroken for my children, and my angel puppy.
