OK, first off, I am entirely supportive of any woman who changes her name to anything for any reason, serious or frivolous, whatever they want. It's your name, so your choice.
HOWEVER.
I am a bit tired of women who, after changing their name to their husband's after marriage, get very defensive and say something like "it was my choice entirely, I wasn't pressured into it either by society or by family. You are denying my agency to say that it was!!!"
None of us are an island. We are all shaped, for good or for ill, by the norms and societal pressures around us. And we all deal with that in different ways. None of us is free from that, it just comes out differently in each of us, on different things. Women are routinely expected to change their name after marriage, and it's seen in plenty of quarters as a deliberate feminist stand when women do keep their own name, a brave/disgraceful (delete as appropriate) snub to tradition.
This was all brought into my mind again by this article, which goes into what happened when a couple of men changed their names, on marriage, to their wife's names. (Spoiler: it upset the apple cart.)
