It's basically a way for a couple to tell each other that they are so sure about this, that they are willing to take a big step. It's not the same as just "being together". If you are just together, she/he *might* leave the relationship with the first BIG fight. There is always a quick exit. If you are married, you work things out, because if someone leaves you break that symbolic bond.
This is ridiculous. If you're in a relationship, you should fight for it as you would have in marriage.
