I agree with some other gals who say to give him some time and hopefully he will come around. If not, I also agree with some gals who say you might have to resort to making him think he got his way and just not giving him all the information. Technically your name does not change until you have your marriage certificate back and you change it with social security and so on from there, so maybe you can get around it by telling him you havent changed it, and then just dont say anything to anyone when you do turn in your paperwork. Not exactly the same thing, but a lot of us are not telling close family that our weddings are not actually the legal one, and we are not being completely honest with them about it, but the point is that its our personal choice, and not anyone elses. Same with your choice to change your name, even tho it's a cultural thing, it is ultimately YOUR business and not your fathers. Good luck and keep us posted!
