Marriage is not a pre-requisite for going through the up and downs of a relationship. Normal relationships with no marriage have ups and downs too, and if there is mutual understanding and affection it will survive anyways. If it doesn't work, well, then maybe it's better to put an end to it and find a better partner?
I guess my question is, why are we putting ourselves in the corner with a contract just to force ourselves to stick around a little bit longer, since you could do that anyways without that same contract?
Maybe it's part of the human nature to go through this, to find a partner that we think will be loved forever, and then it won't work, and we learn from it, and we make more mistakes until we find the real one. Society tells you to find a life partner between a specific age range, but what if it's not true? What if you must make mistakes, you must break up with a partner, maybe only to find out that you both love each other and come back together. Maybe all of this must happen, but we are not letting it happen because of external contingencies.
In a way it seems like we are artificially containing our human nature.
