Marrying somebody means inviting a third party, the State, in private affairs. Now, marriage can be convenient or recommended for religious and tax affairs, particular convictions, and for the protection of kids (then...).
But getting married to learn about yourself and your partner by, in essence, inviting a third party that in typical fashion would obfuscate instead of giving light, reminds me of the guy who wanted to be kicked in the genitals so that he could feel something brand new that day.
