Let me give everyone an example that my W has totally moved on from me. The kids called tonight to say goodnight. W gets on the phone and says "D11 needs your help on a school problem....acts like I will be there always, which I will. Pt is, she acts "as if" there is nothing wrong at all.
Does that make sense to anyone?
Absolutely (all though it is a crazy behavior!). Your W is like an ostrich with her head in the ground -- if she can't see or hear any trouble, then there isn't any. Of course she is going to act as if everything is okay, because she is feeling guilty for what she's doing to you and the family. However, she doesn't want to discuss it with you because she is embarrassed and also because she doesn't want to have to deal with it. She just wants it to be said and done and for it to go away with the least amount of stress, pain, anguish, etc.
It doesn't sound like your W is mature enough to handle discussing it with you. Are you willing to take the initiative to tell her it is important for YOU to be able to sit down and discuss the D with her rather than speak through attys?
