Is romantic love an illusion?

is it just me, or is it starting to feel like romantic love is an illusion? i'm starting to question the concept of romantic love and what that experience is for us as humans because of my own life experiences, but also because the statistics are pretty damning. according to the american psychological association, approximately 40 to 50% of first marriages end in divorce. it's so fascinating to me that something so fundamental to human life seems destined to fail. as i'm maturing and facing these realities, i can't help but ask the question, why? and my brain immediately goes to, well, romantic love must just be an illusion.
