I got married relatively young (23) and in a bit of a whirlwind. I definately identified as a feminist but wasn't really sure what that meant in all honesty, was young and caught up in it all. We did have a conversation about our surname/s...I remember it being a proper discussion and he was initially open to the idea of changing his, rather than me changing mine, but I suppose in the end we bowed to patriarchal convention as he is the only male in his whole family to "carry on the name" (we assumed, correctly, all the women would change theirs upon marriage) whereas I had a brother and an uncle who'd just had a son. My uncle has since gone on to have a daughter - but we're a tiny family so there really are just my 2 cousins and my brother who can carry on our surname.
I had a wobble before the wedding as I identify so much with my family (my mum took my dad's name so maybe I'm just bowing under the convention to be part of my father rather than my husband?) so I have my maiden name as a kind of middle name that never really gets used (our surnames together sound really crap double barrelled). I was right at the beginning of my career so used my married surname both professionally and personally.
I really regret this - while I'm glad as a family unit we share the same name, I wish I'd kept my maiden name professionally. I'm not world famous or anything but I think it might be a bit weird now to revert to my maiden name professionally.
Not really sure what to do about this regret.
FWIW I think DH has cottoned on, as when we had DD last year (we already have a DS) he suggested we give her my maiden name as a middle name in the same way I still have it.
Surely actually the only equal thing would have been for both of us to take one a totally new surname?
