Well, there are a lot of perspectives here. For me, I was happy to change my name when I married H, and I have no intention of taking back my maiden name. For one, my FOO is pretty messed up, and I'd rather not be identified with them.... I do use my maiden name as my middle name, and actually now regret that I don't have my "real" middle name instead.... now that's not a huge issue, but it's enough that I don't have any real desire to have that name back.
Anyway, my married name is also my professional name, and the only surname by which I've ever been known in this country, so that is another reason. And the children are the most important one -- like Cali, I never want to have an issue with that.
Also, I plain old LIKE my married name. So much has been taken away from me, I'm not losing that as well. Like Cali, it's my identity as part of my family, and I am part of my family.
