I understand how Huddy fans got extremely angry about this particular episode (I'm one of them). It was an unecessary emotional rollercoaster.
For one, Cuddy knows House, which means she just shouldn't let her feelings be so exposed in front of House, when they were on the "Are tu Screwing with me" part.
But hey, we can't really blame her. The fact that she committed that "mistake" of exposing herself made everyone clear about her feelings - She cares for him enough to want to let him know - and I feel that from now on things will change, for real (don't tu think that whole "We should kiss now" scene was utterly adorable?).

Honestly, when I read the spoiler from Ausiello about the fondling part, I got all positive for some Huddy sexy moment (who didn't??).
But -BANG- the writers surprised us once more. They turned that scene we were all waiting into an extremely...core-twisting scene.
After Huddy exposed herself, House turned himself into Fulltime-Jerk mode, trying to shove her away with the "I only want tu for sex" - fondling part.
We all know he's always a jerk, but we weren't waiting he'll behave like that, not after the kiss. I guess that sometimes we let our hopes raise too much when we think he's going to mostrar his most affectionate side to Cuddy.
He did it once o twice, but it won't happen regularly, so we might as well forget about absolute sweet huddyness if somehow they get together in some sort of relationship.

Moving on, my guess is that it was really House who managed to get Cuddy's old escritorio into her office (some people have been saying that probably Wilson did it, since it sounds más like his gesture than House's...but the truth is that the contractor thought House was Cuddy's boss; not Wilson) - So House decided not to change Cuddy's decoration after the boob-grabbing scene. He knew he went too far, so he tried to redeem himself.

Now the final part. The fact that Cuddy had probably the worst timing in history isn't that bad at all.
Sure, she got heartbroken (but she's dealt with worse situations all her life, anyway, we all know she's going to recover quickly) - after all, she knows him. She knows how House behaves. If it was some other man she cared for...sure...it would be horrible to see him with another woman. But this is House, and Cuddy must know that whatever he's getting from that coconut-woman won't be a permanent thing.
That scene merely reminded her that House won't change (and if he does, it won't be into the man of her dreams). Although I sense that House will keep sending small hints, to mostrar that he cares for her, but in disguise. Like the thing with the desk.

All that Cuddy has to do is to acept that and let House be the one to make the step adelante, hacia adelante again - it doesn't depend on her anymore, she's exposed herself to him. It's his turn to decide wether he wants to hibernate his FullTime-Jerk Mode when he's with her o if he wants to keep her emotionally away.
