Falling in love is irrational, hormonal, perhaps pheromonal. For me, it is what has driven me to find out if this is the person that will become the relationship for me. It gets me to stay to find out if we can endure each other’s flaws.
Being in love is where you not only recognize someone’s flaws, you realize those flaws are integral to the person you love.
(That does not mean those flaws do not need modification or correction, just that you know they are part of the person you love.)
Being in love for me meant addressing my own flaws to become a better person.
