I just posted about this in the third week of July. I called WH while I was out of town and said, "We have nothing to celebrate, so no cards, no gifts."
Others said that they "changed" celebration dates, but I think that's hard too. We were so happy on that date.
Hell, I've subtracted two years off our marriage....making my son 'illegitimate' - not really, I HATE that term!
Sorry you are going through this.
