It's a promise... To be faithful, loyal, and true...
Marriage itself is not a promise. A promise is part of the marriage process, but a marriage is not required to make such a promise. In my country marriage is a legal/government thing, but largely irrelevant as de facto couples have almost the same rights (if not exactly the same rights, I can't remember where we are at now).
I don't see any point in marriage myself. I can certainly promise my partner that I will be loyal, faithful etc. while we are together, but I cannot promise that I will be with them for the rest of my life. That seems naive to me, as people and circumstances change throughout one's lifetime (as evidenced by the high divorce rates in many countries).
I would love it if I DID spend the rest of my life with one person, yes, that is a lovely idea. But I don't need a marriage in order to do that.
