I think that is precisely the difference.
For me it's that they have been retired for several years now. There's no active partnership right now. It's just the idea that they would probably come together to do shows at some point in the future, not the same thing as the physical and financial investments one makes when one is competing and planning their next season. I don't think it's necessarily wrong to split a competitive partnership either, but IIRC there was some money dispute between Charlie and Liubov that made it acrimonious.
Having said that, this statement from Duhamel is better than I expected and I can understand more of her POV now.
While I don't disagree, I just know that they were both very close all throughout their competitive days and even in their post-competitive days, so the story that Meagan has put out about not even knowing this was a serious possibility until Vanessa had taken the steps to guarantee she could skate for Canada makes it baffling that there wasn't strong communication. I mean, they were the best of friends and they won endless medals together. This wasn't a Krasnopolski situation where he gets tired after one season and just moves on, so I guess I would've expected some kind of discussions.
For me, it's a tough call. Eric can obviously do whatever he wants and he's far from the first skater to do this kind of thing behind the scenes, and it's also hard to know what exactly their fall looked like or how much they were still communicating prior to all of this circulating a few weeks ago. If they had still been talking about the potential of a tour in the fall (whether it happened with CV or not) and then she woke up with a message saying that Vanessa got a release and he was moving forward with that, then I would be a little shocked, too. And it sounds like he held off saying anything at all to her until they got official confirmation that it could happen, so what if that release didn't happen or was delayed till post-Beijing? Would he have still been planning to tour with Meagan since it wasn't a trip to the Olympics?
In regards to Charlie and Lubov, there was a money issue with the LP music but didn't he decide he was done at the end of a competitive season? They may have had verbal goals to continue to Beijing as well, but he changed his mind and didn't let her know until everything was in place. It was shortly after Worlds (that they didn't go to) where it all came out, so I don't know how invested they would've been into a new season. Certainly it stung for Lubov, and I can see why it stings for Meagan.
It's an unfortunate situation, but I'm not bothered by Meagan venting. I've grown up on people venting first through AOL away messages and then through MySpace posts and Facebook statuses, and now it's no different on Twitter and especially Instagram, where almost everyone has moved to in the younger generations.
