Continuing the topic -- I agree that they do not appreciate what they have, or they take it for granted. I think my W realizes what she has here, but I also think it is not enough for her to stop some of her actions/behavior. She wants both worlds.
I'm at the point now, where I realize I can live without her. After BD, I thought my world was falling apart and I must be married with W. This causes you to do things, accept things that are not good. Now, I'm more willing to set boundaries of what is acceptable and not acceptable. I'm also willing to 'risk it all' on enforcing those boundaries.
Oddly, I don't think my W is concerned about losing me right now. Whereas, a few months ago she was. Maybe she has grown too?
