Well HWA, IMHO you dont say anything about anything. Since our sitchs' are somewhat alike (WAW)I will tell you I tried acknowledging our anniversary and only got a response saying she would get back to me on the matter of filing divorce. Which by the way nothing as yet...Then I went thru whether I should email her a happy Bday a month later. I did and when mine came 3 weeks later unbelievably she did not acknowledge mine whatsoever...I said unbelievably because I did not think she would ignore mine.
As far as you have come do you think in your mind you should say anything? I have come to realize my with WAW there is nothing I can say to make anything between us better. She is im her own world and apparently quite happy without me....
