Part of being an attractive man is to be a leader of the family. It is time to step up and be that man, which includes making decisions for the betterment of the family.
I get a wimpy feeling when you post. Sometimes when you think you are taking the road of least resistence, it is just a much longer road with the same result at the end of it.
Long story short, sit down and tell her Your decisions to protect your family. Do not be defensive of your actions, your decisions are well planned and thought out and if she has a problem with it, let her explain why it is such a bad idea to protect these assets for yourself and your son.
