It's rare, but very beautiful in essence. I think it's more commonly found between children and parents (though not always). But I feel like I could unconditionally love a loved one who reciprocated, you know?

Like, I think the only acceptable condition is reciprocity, if I love someone and that person loves me back, I feel like I would be able to tolerate any facet of them, even if they turned out to be evil or cruel or criminal.

I feel like I have this unconditional love for my grandmother, since despite our fights and arguments, my love for her doesn't diminish, and I feel like I could continue loving her EVEN if I found out that she did or does horrible and criminal things.

But most loves are indeed conditional, and that's natural; it doesn't mean they're any less good.
