Sorry about your situation. Mine is very similar so I understand what you're going through. In fact, this past weekend was my 7th wedding anniversary. In the first few months post-BD I tried flowers several times they did not work. Now I don't bother and have gotten to a point where I didn't even acknowledge the anniversary and you know what? The day wasn't as much of a trigger as my family and friends who reached out thought it would be. I went to a lake house with friends instead of my W, and it was fine...life goes on.
Hang in there!
