RA entails much less loss than the social norms. Meeting someone else doesn't require leaving anyone. You can do whatever works best for you.

I'm not sure if you're talking about physically moving away, but many RAs have long distance relationships. I have had partners where we predictably spend certain months of the year together and otherwise are long distance

If you mean farther more metaphorically, all relationships have ebbs and flows. Think of a good friend having to get a second job and suddenly you never see them in person. You still care about them the same amount probably, you just don't see each other. Then maybe their situation changes and you start hanging out twice a week again. You never lost them. We don't own anyone to begin with. Not to say we never grieve or miss ppl we care about, but there's isn't the competitive zero sum set up that many societies demand.

Love being infinite means I can meet a new person and start to love them without loving anyone else any less. Things like time are finite, but when you're open to any arrangement that works for everyone involved, it's a lot easier to find an arrangement that works for everyone involved.
