<human>: Could you distill the essence of the text into 1-3 sentences?

Nine months ago, my girlfriend proposed to me while we were at a music festival. It was a fantastic moment for the both of us and we have been in bliss ever since. We have been together for six years now and we have reached that point where we want to get married and start a family. 

So, I'll start the story that my title says I'll tell. A few days ago, I sat down with my girlfriend in our living room and after we finished watching a show on Netflix. I told her something that has been in my mind for a while, I said to her that I want to take her last name when we get married. At first, she laughed, but not in a mean way, just a more nervous laugh. She said to me that she has never heard of that before, I told her that it has been on my mind for a while. I told her that I don't have any bad blood with my family, I just like her last name and I feel it would make a great family name for us. 

She was still unsure about it and said that it does not seem right, but she was glad that I told her about it. The way she talked about it, made me feel a little sad, but I understand why she had such a reaction. It's a pretty uncommon thing to do, but I do think her last name would make a great family name. 

The last few days, she has been thinking about it more, but she still can't get her head around it. She says it's not traditional, but she does not want to make me feel bad about proposing the idea. It's something that we seem split on and I think we can get through it, but I think we need a little more help about it. 

I've told my parents about it and said that if that's what I want  then do it! I've not heard from her parents about it, but I think we would both tell them soon. 

Any advice?
