That's a fair point, but with that mindset - marriage is not for you. Why would you get married and pledge your life-long commitment ("for good and bad... until death do us part") if all you really mean is "until I'm 100% satisfied".

The idea behind marriage is (was?) to start a family. The person you married becomes your closest family, and you don't abandon/replace your family even when things get rough, you work it through. Can you imagine anyone abandoning their child or mother because 'things weren't very great between us lately'?

But sadly, that only worked when divorces were rare and socially unacceptable. You simply had no other way but to make things work and fix your relationship. Currently, when things go bad, the first thought is "am I better off alone?" or "would I be happier with someone else?".

Relationship dynamics are a motherfucker. With loose social/religious norms it's hard to pull off a lifelong relationships, unless both parties got it figured out and know exactly what they want. That's why marriage rates are higher (and divorce rates lower) in the upper class, when people tend to be more intelligent.

In short: Don't get married if you're not ready to commit 100%.
