Celebrated my thirty-third anniversary a few days ago. I celebrate it in some way; going on a picnic, making a cake, a restaurant meal, something to mark that day a long time ago where I wore a wedding dress and carried flowers and my husband wore his then one wool suit in summer and was so distracted he forgot to pack any underwear. (He likely remembers the rash the most.) Where we promised to care for and love one another in front of several hundred people.
It's the promise that I celebrate, the oath that I took. As an Aspie I keep my word, which is important to me. Promises are not something people consider important, but I do. Marriages are and can be complex things, they require a lifetime of working at a relationship, to understand one another, to get along, to continue to care for one another during fights, misunderstandings, sickness, anger, loss. Many people give up, divorce or separate, for their own complex or simple reasons.
I've worked so hard to understand another person for such a long time, that even when I'm angry at him, I still care for him. I celebrate not giving up and I celebrate being with a person I couldn't possibly live without. Someone who cares for and sees me for exactly who I am, and who I see and care for as exactly who he is. That is something to commemorate.
