I just think that although she does some talking about thinks and the relationship, all her little actions indicate she wants it over but is afraid to pull the trigger. Often the one who is unhappy just leaves, blames the left behind spouse who is now dumbfounded by this major life-upsetting event. The one who left has what he/she wants...freedom from you. What she/he won't do is finish it off because she doesn't have to, she/he now has it just like they want it no matter how it looks.
The left-behind spouse unfortunately will eventually run out of energy, money, or whatever, see the writing on the wall and call the attorney for the divorce because he/she finally realize that his/her husband/wife is gone and never coming back. Best to stop hoping and do something else. So sad that we weren't given a ten year warning that things were headed down the wrong path, or maybe things were actually very good.....and then a 3rd party entered the scene and all hell broke loose!
