The reasons against:
- I don't really think it's any of anyone's business
- I don't think it should be of relevance to people or be upfront as something about me - for example, I'm a Ms., and a Ms. I will remain - I don't think my marital status should be so on display.
- My status is "in a relationship."
- The status applies to men and women
My overall feeling, however, is that I just don't want to change it. As we come up to six months of marriage I have enjoyed every bit of it, with one or two notable exceptions aside, and it hasn't suddenly changed me as a person in some of the ways that I worried previously. But my fundamental unease at the centrality and import society and, of course, many of my acquaintance place on being married, along with the expectations of me as a married person, hasn't altered at all. So it stays the same. For now.
* Strangely, in the past few years I have noticed an increased acceptance of the term "partner" for hetero couples. Of course, this is snatching the term from gay couples, but I think it so nicely describes a relationship that I'm pleased that there is something that isn't just boyfriend/girlfriend, dating and marriage. There's now room in the straight couple catalogue for that option.
