Oh, the ships are burning...there'll be no turning... back for you an me!

I had a conversation the other day that is still bothering me because I didn't feel I defended my case as well as I could have had I been first given three days to replay it all in my head and make up all the right answers in retrospect.
Egh.
Well, anyway, we somehow got on the topic of marriage and I mentioned that Luuk and I decided before we married that divorce would never be an option/solution. The response was that we were setting ourselves up for disappointment because what if something happened and we did end up divorced?, we would feel it was a personal failure. I said yes, I guess I would see it as a personal failure, and then proceeded to try to defend what I had just said with a bunch of unconvincing arguments that I have much improved in my head over the past few days.
But what struck me was that "personal failure" bit. Is that so bad? I would imagine, at this point in my inexperienced life, that if we ever divorced it would be because one or both of us hadn't done everything we could to not only stick together but to love each other (and I never met a couple who divorced still loving each other). Are we so averse to responsibility that we would hope not to feel like a failure or like it was our fault should something go wrong? (And we say "should something go wrong" as if it were some outside force that we had nothing to do with...). That we could ever take seperate ways and not feel any guilt or responsibility seems impossible to me; and if it is possible, then I suppose I should no longer be surprised at the state of relationships these days.
When Luuk and I said "no divorce", it wasn't without the recognition that things don't always go as you expect/hope, or that it won't always be easy (though I must say so far it's been a breeze...maybe it helps that he's out of the country...ha..ha... just kidding...sniff, oh, I crack myself up...). But "no divorce" is part of "commitment", "loyalty", "faithfulness". (In Dutch there is one word that seems to encompass them all: trouw). If we are both commited to each other, commited to sticking together, to helping the other grow, to encouraging and supporting each other, etc., and if we are loyal and faithful to each other above career, friends, and blonde bimbos and handsome colleagues, then it seems to make sense that divorce will not follow. But making the actual decision to never consider divorce does two things: it forces/enables (depending on how you look at it, I guess) us to look for other ways to solve things if we ever get to the point of not being able to stand each other, and it gives us more space for trust (or reduces fear/distrust), I think, given that we both know the other will not be thinking divorce or looking for a way out but will, like me, be looking for a better solution.
So, basically, I think that removing that option, or burning that good ole cliché ship, creates the space where a relationship can thrive in complete trust. And if something goes wrong, then it really is our own fault and we better take the responsibility for it or we'll never be able to patch things up. Doesn't that make sense?
