To be honest with you, at 24 years old, I think you're too young to be thinking about marriage. You both should be enjoying each other's company and seeing where this leads in the future. For now, enjoy life and don't think too deeply about all of that.

If you guys are together after a few years and you both are still feeling differently about what you both want in the long term, then that's when you should be concerned. But if the relationship is in fact a loving one, then you both would come to a consesus that would work for both of you.
