When you and Bob marry, will you want to be known as Mrs. Smith? Why or why not?
(Anyone can answer, not just straight females, I don't want to exclude anyone, so if the question doesn't fit because of the genders I used, then just twist the question so you can answer. :-) )
Personally it makes me feel uncomfortable, like I'd be losing a part of my identity and replacing it with hers, since that was her name for so many years. On the other hand I am very traditional and would love to take my boyfriend's last name. I just don't want to be known as Mrs Smith the second, as that name is still, at least in my mind, associated with his ex wife.
