Sorry to read about the D, Harvey. I can tell you it's just a piece of paper (it is,) that people do sometimes reconnect post-D (they do), or that it is your W's loss (it is), but I'm sure that is cold comfort right now.
Don't even bother yourself worrying about how she is reacting. There is an expression in Spanish "Caras vemos, corazones no sabemos" (faces we see, hearts we don't know.) Who knows what is going on underneath the facade. But, that isn't your problem any more. If you are keeping busy and comfortable in your own skin you are in a great place to move forward into the next chapter of your life. Keep GALing and working on yourself.
