G, listen, you are new into this. It is hard stuff and it takes time.
You cant be yourself around her because you are worried about what she thinks and you dont want to do the wrong thing.
Detaching is the most difficult part of this. It is counterintuitive to how you think you are supposed to act.
But it is the key to all of this. It allows you to focus on you and who you want to be regardless of what she says or does. What dbing helps you do is become the best you, which is always the goal. And sometimes it saves marriages.
It helps if you think of her as a neighbor. You would be friendly, light, and go about your life.
