This is why the original question is tricky to answer: what does the OP mean by love.

English is bereft of vocabulary for this. I'm reminded of CS Lewis's Four Types of Love or Four Kinds of Love. Not that I agree with everything he writes.

But even Eros implies more than just feelings.

I don't know what you mean by Love = Feelings

That sounds like infatuation to me, since you also say (I think) that these feelings you mention are experienced on their own, outside the context of a relationship.

Oh, and by the way, I don't think that love can exist outside of a relationship.
