I don't want to let my wife take my last name
Why can't she have your last name?
I don't want her to take the name of someone that I hate. My mother gave me my name
I'm sorry your last name is giving you a lot of trauma, so you don't have to keep using it. You can use your wife's last name instead, it's perfectly fine. You don't need to attach yourself to something so traumatic if you don't have to.
Yeah that's fine but she really wants to take my last name.
You two should have a talk about it. Your wife does not have to take your last name, there are some people that take the name of their wife instead.
