Unfortunately, no, you really don't. You may have known the previous W, the one you married, but you don't know this one. This one is a whole new incarnation and creature. She looks like your W and talks like her, but inside she's someone else. Whatever the reason is for that is different, but trust me that you don't know her.
It took me about six weeks to realize that my W is not the person I knew. I'd had the feeling for months but ignored it. Then after dropping the bomb the need for "keeping up appearances" went away and she changed in front of my eyes into what she is currently.
I can't predict my W anymore or hope to know what she's thinking. This is what makes trying to read into their actions so dubious and frustrating. It's like reading a book that was translated from another language, only the translator wasn't very good an English.
There are moments when old W appears. A few more now then when this started. But put away the old paradigm... it's gone. You are in a whole new ballgame now.
