Romance is like rizq

Remember when Omar Suleiman said that? I watched it a few days ago and that got me thinking( I don't even know if this is something I should be thinking about with the chaos in my life but nevertheless it's something I'm wondering about.)

How do people stay in marriages without romance, isn't that a necessity that keeps marriage happy? Is there more to marriage than that? I'm clueless and I am not really looking to get married anytime soon, but just how?
