I think love is a congestible good.

It is not a rivalry good because when somebody loves someone the first time and it didn’t work, that somebody isn’t a ‘used’ good that will have depreciating value, in fact the learning will make him a better lover as long as he already moved on. A rivalry good is when consumption decreases the value of the good for the next user.

It is not an exclusive good because we don’t love just because someone is giving us reasons to love. Love can be one-sided. And yet it is still love. It doesn't discriminate to the ones who cannot pay the price of love, which is the very essence of exclusive goods.

And so therefore it is a congestible good, a congestible good is a good that is affected by congestion or too much users using it. It doesn’t depreciate the person like a rivalry group if it isn’t congested. Just like in love, you should only love a single person. Nor it discriminates the resources of a user, because it has a fixed price and is efficient if it isn't congested. On the case of Love, we should only love 'the one', to avoid congestion.
