It doesn't. Unless it's important to your husband. If it's important to your husband and it 'hurts' him, then it is a reflection of your commitment if you refused to change it.
For example,
I hated my husband's family and really liked my maiden name like you do. And then LJ said, well I really want you to take my last name and I didn't want to do so. Then I think insisting on not changing it would reflect on my commitment to him as his wife. Because as we all know, it's my duty as his wife to obey his wishes.
