Why get married?

Savannah • 25 | married 💍 | girl mommy

My boyfriend has said that he doesn’t really see the point in getting married. And the only thing I can think of is because it’s what everyone expects us to do. We still see each other being together forever and have even talked about having kids in the coming years. I mainly wanna know if anyone has decided not to get married to their SO, but still have kids and build a life together and it works out?
