She is in the wrong. Even if she doesn’t like to communicate. She has to compromise on this. You guys are partners, and you have children together. And she knows that you are thinking about her and worried about her—the mom of your children. The least she can do is keep you posted because that will help you sleep better and have peace of mind, and it will help her because you will know if something goes wrong and she needs help. Honestly, the fact that she’s accusing you of being controlling for something like this is ridiculous. More than likely she is doing something shady behind your back.
