OK, I can be a very dense man. Just ask Milady. I often don't understand things.
I am very confused by the term "committed relationship". It seems that Peter Orszag was in a committed relationship with woman number 2. He wasn't committed enough to marry her (the jury's out on whether it was mutual or not), and wasn't committed enough to stay with her after she's pregnant. He's already in yet another "committed" relationship with his new fiance, a couple of months out.
I see no commitment here. He stayed as long as he was getting something out of it, and then left. I would prefer the honesty of "it was only about the sex and food" than "we are in a committed relationship".
Of course, he could be using an alternate definition of committed: "To place officially in confinement or custody, as in a mental health facility". That would work with Michael Savage's theory that current liberalism is a mental illness.
