I'm currently trying to decide this myself. I think if I go back to my maiden name I'll have to somehow convince XH to let me change the kids names to mine aswell. I dont feel bad about taking away the "carrying on the family name" as his dad had 4 sons & other grandsons to carry on the name, my dad had 3 girls so no-one to carry his name on. DS also has XH's dads first name as his middle name so he will still carry that name forever IYKWIM.

To me its important that my kids have the same surname as me, its personal choice, this is just what I want for us

Good luck
