I believe in keeping one name for life. When I married in 1980, dh said he thought families should have the same last name. I disagreed, but said if he felt strongly about it he could change his name. He didn't. If he had insisted I change mine, I wouldn't have married him, because that would have meant he was an MCP (who remembers what that stands for?). Fast forward to 2 years ago when we went to marriage counseling (we should be divorcing this year), and among his complaints were that I didn't change my name and would never agree to a joint bank account. The bigger problem was that I married the wrong gender - the other things were just symptoms. I did kind of always resent that both kids got his last name. I wanted my last name for one and his for the other.
