I would agree with lonelyolive. My wife and I still joke, and talk about things on a near daily basis as she still lives in the house. However there is a distinct emptiness.
Its painful to skate around topics that include dreams and plans for the future. Even short term. Talking about concerts/restaurants/movies, etc that we once would have enjoyed together also is something we avoid consciously. Can't always talk about her day or night, as it could have included OM.
Knowing that someone else is getting to enjoy the gifts of my wifes time. And that she is sharing those dreams with someone else is painful.
Also my wife has made it clear that she is frustrated that we are not moving faster in our seperation. She wants to start living the fantasy she has in her head. 1 week ago she told me she hated me, and that she hated how "perfect" i am all the time now. She apologized, in her own twisted WAW way. Today she has called me 4 times on her way to the airport, joking and laughing about this and that.
I know she is in a fog, and I have chosen to love her unconditionally. So in my interactions, i try not to think about the hurt, and try not to expect any positive reaction back from her. I have seen a lot of positives, but in her mind Fantasy Life is her only option.
