Too soon?

I’ve been with my girlfriend for almost a year now. I feel in my heart that I’m in love with her. She’s the kind of woman to push me to remember my goals and never give up on them. She offers to bring me medicine and fruits and soup when I’m not feeling well. I can very easily tell that she cares and we’ve talked before. We have agreed that I will eventually take her name if we decide to get married. She is absolutely stunning and bold. But is it too soon? We’ve been through a lot together as both families don’t agree with our lifestyles. Any help would be great and I know that obviously we are young so it isn’t dire. But I feel excited and nervous to say I could marry her. Is it too soon?
