It seems to me you are watching your W too much and putting too much stock in little signs of "friendship" that may or may not mean anything with regards to where she is or is thinking of going.
Pulp- I have made this mistake over and over again. My W and I would joke around, flirt a little, and get along great and I would become hopeful of a potential R. Then she tells me she still wants a D.
I feel you can appreciate and be greatful for the good times and the fact that you can be friendly and enjoy each others company from time to time but do not set yourself up for major dissapointment by projecting future expectations.
I am finally aware of this dynamic and have been trying to not set any expectations but it is difficult.
