I personally tried to ignore my anniversary last year, but H wanted to recognize it. I told him I had plans that didn't include him. He told me to cancel them, it's a weird day, but we should do something. My best friends sent me flowers. H bought me dinner. It's turned out well but all of it was an internal struggle. I'm very interested in finding out what your W decided to do to mark the day.
Fun fact: "Traditionally, the 10th year of marriage is marked with tin or aluminum. Both materials represent the durability and flexibility needed to sustain a loving union."
