T, I dont really like labels. Because no one is one size fits all.

Whatever it is that is going on with your wife clearly is not just someone who wants out of a marriage. There is obviously something very wrong.

You know what your life was like for all those years with her. While there may have been things you didnt realize or should have paid more attention to, the feelings and memories you had were real.

Because she is is crisis, she is panicked. She knows something is wrong, but, doesnt know what. So, she is blaming the person most important in her life.

If I can get out of this marriage, then I'll be happy. When that doesnt work, she will try something else. All with the hope that it will fix what is wrong.

It is only when she looks inside that she will be able to begin to heal.

She needs to walk this journey and the best thing you can do is let her.
