You didn't do anything over the top. In fact you did the exact thing she did...state what you wanted. Stop feeling bad about it. It's time for you to get your b@ll$ back from her.
Stop saying that you are trapping her, etc. you are not. All you're doing is making sure you and your kids are protected. She's on the emotional high of the OM. Remember that case about the astronaut lady who left her family and drove cross country wearing a diaper to get to the woman whom she "truly loved"? That's where your W is now.
She sees you as an obstacle and wants to destroy that. How do you combat that? By being the rock. Look at her as the crazy person she is at the moment. In fact, I would have called the police. She could very easily flip things around and say that you "restrained" her.
You might think that your sitch is different, but it really isn't. Been there done that. All of the WAS's who have been caught with an OP have blown their lids and then try to flip it to the LBS and say they are holding back their happiness and crap.
Stand strong. You can do it. Protect yourself and your children. It's cases like this that you hear the parent kidnapping the kids and taking them to another state. Put your foot down.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
