Is love a social construction?
Love itself is biological, but how we act, who we fall in love with, how we court, what our expectations are, those are all at least partially social constructs. There are bodily changes that take place when you fall in love and when you’re around someone that you love. Touching and looking into one another’s eyes release chemicals that strengthen the bond. But not every society expects couples who are in love to behave the same way. Heck, not every society even cares about love. Our own didn’t until relatively late, particularly for the upper classes. Some cultures expect you to have one love, forever (sound familiar?), while others are far more accepting of multiple partners over a lifetime.
