I tried this - and was met by self defeating comments - so I quit saying anything. And now today, I quit saying anything at all.
Shell, whatever you do, do it for you, not for the outcome. If you feel you need to honor this day, do so. If you feel too angry/bitter/mistrustful/whatever to acknowledge the 30 days, don't. She'll know if you are sincere or not. We women know these things.
BTW, congrats to you for sticking it out another 30 days.
