VaAugusta, it may actually be an important thing to say. It's important for people to reflect back on their situation. "This person on the internet says I'm right, so I must be!" is a more common thought than you might believe. By prefacing it with statements like, "I don't know what your relationship is like, obviously..." and so on, it turns the statement to bear on the asker's perspective.

I don't think anyone said "He obviously doesn't care, so you should end the relationship as fast as you can." What is being said is that, based on the information we have, he's being unreasonable, and if he can't see that (and see that it's affecting her negatively), then she needs to do some thinking.

I understand the idea of the impossible task to give her more punishment (which she wants), that's why the nuances of the relationship matter. Also, if he doesn't realize how long it would take to compose 1 million words and he is illiterate, I say that's totally grounds for immediately ending the relationship, with complete and utter sincerity.
