at least for Wilson, Cuddy fares less well
House would say that from her pov it makes no difference. Her choice was whether she'd give Wilson her liver to enable him to survive, not what chemo Wilson was getting. Had House given Wilson less cetuximab she'd never have had that choice, which might have made things easier for her, but not necessarily nicer.

I think Wilson realises that any match between them wouldn't have lasted
He was pretty much aware of it from the start, which was why he wasn't keen to keep the baby in the first place. And unlike Cuddy, who has been preoccupied with her own health and the problem of providing for Rachel, he has noticed that Amy has been conspicuously absent lately. He wanted it to work for the baby's sake, not for his own, but he's hardly surprised that what he gets isn't what he wants. Amy hasn't been acting wisely till now, but exploding the myth of a workable relationship between herself and Wilson was undoubtedly the best thing to do,

Much better than Garfunkel :)
Really? Now that there's competition in the form of 'Precious Harmony' I feel that I should have gone all in. :)
