Love is a drive that can settle into a lasting bond; limerence is an involuntary obsession fed by uncertainty. Love survives being sure of someone — limerence often dies of it.

What each one means
Limerence
Limerence is an involuntary state of intense romantic obsession, in which your mind fixes on one person and aches for a sign that they feel the same. It runs on uncertainty rather than intimacy — which is why it can burn hottest with someone you barely know.
Love behaves less like an emotion than like a drive — closer to hunger or thirst than to sadness, and in some people it is still firing after twenty years.
