1. Making sense of it all is futile. There is no sense to be made and the sooner you come to terms with it, the better it will be for you. I know you won't trust me on my word, but it's OK, you'll get there eventually.
2. Yes, we have all gone through it. Our spouses became an all together different person, similar to an alien invading their bodies. We have all spent COUNTLESS hours with the WTF look on out faces. Again, futile endeavour.
3. Look at the W's eyes. You will notice the absence of life in them. They are called shark eyes.
4. Again, we all went though the same $hit you are going through. What is remarkable is that all of our wayward spouses do the same stuff in similar order, they all use the same words and actions. In fact it is so much similar it's eerie. This is why it is called a script. They all follow a script so to say.
