It's not as simple as not living up to your commitment.

Yeah, mostly it really is. I'd make an exception if there is abuse or cheating going on, but yes when you get married you are signing up to be a caretaker to a sick, unstable, dying, unemployed, depressed, failing, whatever spouse. That's the deal. If you aren't prepared for that, don't get married.

If you aren't prepared for that, don't get married.

Have you been married to a mentally ill person? Probably not. Why so quick to judge? (And why the arbitrary exception for abuse or cheating?)

How many people think about the possibility that their partner may become physically or mentally ill when they get married? Most people assume their life will be great and don't really think about how they would handle really bad situations later on.

That's incredibly idealistic. As thasmin says, people don't know themselves when they're getting married. I think you read it as a justification (rather than an explanation - which I believe is what the thasmin meant) of why people leave.
