You set up your own weak straw argument and then knocked it down with a conclusion that is entirely unsupported.
Since when is love relegated to the romantic sphere? And or since when is that definitely the strongest type of love? The topic is so much wider, so much more elaborate than your set-up pretends.
There's no illusion - love is a complex, durable emotion and is as real as (typically) shorter duration emotions such as anger, fear, joy, etc. Your emotions and thoughts aren't illusions, they're real.
