Sorry, but expecting someone else to remember every date that their partner finds important (the exceptions being big things like wedding anniversaries, children's birthdays, and your partner's birthday, etc) is just unreasonable in my opinion. I am happy that my husband remembers how we met, not which damn day it was on. I am happy he remembers what our first night together was like, not the exact date. He remembers how he proposed, and we can reminisce about the intimate details 15 years later...which is what matters to us. Sure, I recall the dates but, to my husband and I, what happened is what should be relevant and remembered. OP If you can remember how incredible your first time together was, and can recount the intimate details....why can't she be happy with that? She probably needs to get over her date obsession, because chances are she remembers only the ones important to her...but what about the ones that mean something to you? Do you have any dates that are important? Does she know all of them?
I found that the males have been far better date keepers than I. The one exception was with my beloved ex. We tracked the day we got together by moonphase. It was the day prior to the full moon, and we never said anything, unless we saw the moon, so it was a giant reminder. (Yeah, I did have moonphase on my computer, and desk calendars) How about a move that will almost exonerate you, and give you something You can remember? Take her someplace very new to both of you. Pick a date you will remember. Then you can"jokingly"/romantically remember the event. But do get the non standard anniversaries into a calendar. They must mean something to her. Ask, get her to talk, in a conversational way, not accusatory.
I don't know how you fix the dates thing, but I do know that it's trivial compared to the task of fixing the gulf that will result from refusing to talk to each other for days at a time. Giving your spouse the silent treatment is childish and accomplishes exactly nothing except building resentment. My opinion is that's what you should work on first.
haha! I'm terrible with dates too! This is true on the whole I think. I don't give a crap about dates. Other than Christmas, Christmas with the family is nice ^_^ And.. I dunno I mean I like getting things for my birthday but I could live without it.
