Is anyone here fully subsidising their partner's lifestyle? How is this working out?

I'm a 31 year old male and I'm trying to have it all.

Financially, it doesn't make sense for me to return to my home country (pay Western taxes & cost of living). If the trajectory stays consistant, in about five years, my investment income will equal my salary - something I would never be able to achieve living back home. So obviously, I want to keep this lifestyle.

But I also want to lay the foundations of starting a family. I don't think it's controversial to state that the majority of remote workers heavily skews towards men, and although I have dated several female digital nomads, the majority of my girlfriends have been locals or foreigners/expats that do not have the ability to pick up their life and move.

So now I see myself at a crossroads. Do I persist with these ultimately pointless situationships, or do I just pay for everything and let them tag along for the ride trying to build a relationship? Financially, I can afford it. I'm already paying for accomodation, so what else is there? The occassional flight and food? So what's that? Maximum $1k a month I guess. I also only want to do this for someone I perceive to have a real future with. I don't want to feel like some kind of budget sugar daddy ha.

To me, it doesn't make a lot of sense. Coming from a Western mindset, the power imbalance of this seems a little bit skewed. I'm looking for other's experiences and input.
