I never changed my name. Too much trouble, and it's not worth it to me. Got divorced, and it was so much easier that way. lol
I'm not a fan of the hyphen names. Either you give up your name or you don't. Don't half-ass it.
I did come across problems, though. For instance, people called him by my last name when I would book things, and I used to go through more questions and security crap to get info about a credit card or something. When I went on his insurance, they wanted proof that we were married. We had to come up with proof on a few legal things, but it was better than getting a new social and going through the BS to change the name that is not important to me. To me, it's a form of "ownership," so I will never do it. I dont' really have any issue or see a big deal if others do it. That's cool. But, for me, I have too much of a history with men who wind up milking off of me than the other way around, so I haven't respected many men I've been with to go out and change my name for them.
