My SO [25 M] and me [25 F] are incompatible opposites, but love eachother very much. Reason to end things?

It's fine to be different but there needs to be some overlap in general direction and acceptance of your differences. It seems you're the dreamer & he's looking for the standard American dream. In a nutshell, there's nothing wrong with that but it concerns me that he thinks his view is sensible and yours is ridiculous.

You should ask yourself (& him) if you're both fine with different savings rates, fine if you're away more often, and what a reasonable household looks like from both your perspectives. Also do you have ANY overlapping interests? You're both going to change over time and may reach an equilibrium that's somewhere between both your needs... but if you aren't growing together through shared goals and (some) hobbies, then you'll end up as roommates rather than partners.

For what it's worth... I'm the more adventurous expat focused on personal finance, reading, fashion, travel, and social activities. My ideal life would be an apartment in the city, and traveling frequently across Asia for work. My partner is a homebody, very into brewing & so on, hates reading, enjoys tinkering, hates travel. He also likes a citylife but for different reasons than I do. And I find his hobbies interesting but he is not really into my hobbies. We agree a city apartment is great, we're both 'meh' on children, and we both like the idea of carving out separate pieces of our lives (ex. i travel frequently) and having some overlap as well. It'll change as we change, but ultimately we can both envision a happy life where we can both pursue our goals but also be a partnership. And that vision is shared, understood, discussed and there isn't one person giving up everything for the other.
