> there's not really such a thing as a bad marriage so much as selfish participants This is absurd. It's constructed of a series of suppositions, only a few of which I'll address. First is that people are static. This simply isn't true. We all know that we all change - not just in age, wisdom, and so on, but in tastes, politics, religious dedication, and the lines we draw between wrong and right, just to name a few.…
Gotta disagree with you: marriage is a contract, forsaking all others, so long as you both shall live. Divorce means your word is worthless, and that your own wants are more important than your word. It IS a personal failure, but go ahead, rationalize all you want.
Not everyone views marriage as a contract or as something that cannot be broken ever. The legal status of marriage in a jurisdiction != how people feel about and treat marriage.
> Divorce means your word is worthless, and that your own wants are more important than your word.
Giving your word on something isn't a clause that requires you to give up your own wants and needs. For example, if you married someone and one day they become abusive, you are not obligated to stay and take said abuse.
> It IS a personal failure, but go ahead, rationalize all you want.
This attitude is so unhelpful and smacks of a superiority complex.
