Been there, done that
I feel for you believe me. We went through the same things. You did the right thing by going to the police station. I hope you filled out a police report. Even though the police won't technically get involved in a domestic dispute, document, document, document. It has saved out butts more that once and we now have custody of my husband's oldest son and we are going back to court in a few weeks to get custody of his daughter because of his ex pulling the same stuff. Kids get wise to that crap, just rise above it and be the bigger person and you'll come out the hero. Believe me. Enjoy your free time, and when your husband gets home, go (with a police escort, and they will do that) to pick the kids up and enjoy some family time. the law is on your side. Like I said though, keep track of all this stuff she does, judges love stuff in black and white and you may eventually be lucky like us and end up with custody of your husband's kids and his ex will end up alone. My husband's ex tried the same stuff with getting it court ordered that I couldn'd keep the kids overnight (my husband works third shift) and the judge wouldn't even let her bring it up in court. She was informed that I was a legal guadian, period. I live in indiana, so I don't know for sure if it's the same in your state, but I would be surprised if it wasn't. Keep your chin up. As long as you keep your emotions out of it and do what's best for the kids you will always win, believe me.
