YNBU to have dreams and aspirations for your relationship, and YANBU to want what you want.
However, if he does not want these things, it doesn't necessarily make him a bad person, he might just not be ready for all that. I don't think being cross is the way to go. He might well be younger, more immature, but people develop as they develop.
what you have to decide is where your dreams and aspirations coincide. If you can frame it that way, maybe you can find a way forward?
If they don't, then it is sad, but that is no reason to have rows and begin to hurt each other. He needs to understand how important this is to you, not that it is something that he has to do to be with you. However, if he is not prepared to be open to changes, then you can tell him that you no longer consider the relationship to be a long term prospect for you, and you will continue on that basis. Or not. But it doesn't have to be a big drama.
I hope that makes sense.
