Your WAW has got some stuff to work out....and it will take time. The best thing for you to do right now is leave her alone and focus on you and the kids. Spend your time in making a new man out of yourself. What were you like when she fell in love with you? Get in shape, eat a healthy diet (b/c that affects your emotions/thought pattern)start working on your grooming and wardrobe. Look good when you are home. Even if you are bearfoot with jeans & T-shirt....make sure you are shaved and have hair looking hot and you smell good enought to make a girl swoon.
Now a word about your kids. You are the first man that ever entered the heart of your daughters. Do you realize how important that is? It will be the primary basis of their choice in a H. They need their dad to be a strong leader.I would suggest that you do not ask them to help you be a better man. They do not know how to do that. It is not their responsiblity. It is yours.
I suggest that you ask your children what their emotions needs are. I can tell you this much, they need your personal time. I understand your working and how that is what you saw as being a good providers, father, etc. That is what a father should do. But your children need you to be with them, especially now. If you don't know what to talk about, just "be" there with them. Ask them what they would like to do and if they say they don't know.....get them out of the house and make a day of doing something special.
Your M does not have to end in D. Much of this will depend upon you. While she's trying to escape in her fantasy world with OM, you are changing into a wonderful person. When the A falls falt, she will see you and your changes.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
