I just can't figure out why if she's so happy with OM she's trying to be friends??
This is going to sound harsh.....
Why wouldn't she be your friend? She doesn't have vested interest in you as a spouse (at least not in her mind right now), she is not attached to you emotionally. If she can retain you as a friend, a lot of her guilt will be diminished. She gets to live her fantasy life with OM, plus she doesn't have to feel bad about hurting you. It's a win win for W.
