<human>: My girlfriend has a last name that is a very common hispanic last name. For instance, Garcia. I have a very obviously white last name.

I am not at all saying that I "demand" her to change her last name. She posed the idea that I could take her name instead. But I am in a field where I'm likely to publish research papers. She's in a field where she is on the path to publishing fiction.

She cried for a little while tonight when I told her I don't think I'd like to change my name. It wasn't a big deal cry, more like misting up, but she did say that she was sad she doesn't think we are going to be able to "share" a family name. I felt sad too, honestly. 

If it wasn't for the science publishing, I would be more than happy to take her her last name. But she said she doesn't know if she could ever take my name because she feels it would be erasing an obvious link of her heritage.

For some background, she is white passing. Most people don't see her as hispanic. They often times don't believe her. But she is, and it's a huge deal to her, and I don't have that kind of connection, so I understand. 

We are not having kids, so that is not an issue or concern.

Is there any solution to this that we don't see?
