folio44 makes the following point.
I have not brought up our anniversary date since, 5 years later and I never will.
I tend to agree, uncertainly, but that is the trend here as well.
I also haven't brought up our anniversary in years, either one of the dates we used to celebrate.
I know, deep in the recesses of my brain that was so severely mindfucked with by being lied to and gaslit, that I spent 18 years working to make those days special, making sure I was not working, making sure there were no distractions, etc. (Honestly, I was the husband who never forgot birthdays and anniversaries, made all of them special, and took all my children's and wife's birthdays off from work), Then, to have all this happen. I have to admit, I've got no fucking clue what to do now.
So, I figure she needs to step up to the plate on this, it is her turn to carry the torch.
Problem is, she can't do it. Confession was 10 years ago. Affair was 19 years ago. She "tries" but doesn't know what to do either, and she can't bear to talk about any of it. Even when we talk about these dates, she is at a loss, she usually brings it up a few days before, but doesn't mention any of the actions that lead it to be so complicated.
So, if you are struggling with what to do, perhaps the best thing is to do nothing, celebrate nothing, and treat them like any other day. I don't know if that is right or wrong.
I used to believe it was VERY important to maintain these days and the memories of them, etc. However, I'm no longer sure about this, and from 10 years after the final D-day, as I said above, I've got no fucking clue.
