No I can't imagine how when someone is all alone with just the quiet of their own mind, how they could ever feel like they got what they wanted, and I think that after a certain period of time they would know this, even if they never admitted it!
See, my H is talented enough to combine the 'its not my fault our marriage failed' with 'I miss my kids...boo hoo'. When he gets sad leaving them (to go sleep at his dads, remember. Where he WANTED to go), he says 'You are the one that won't let me stay here.'
Here's 2 tissues. One for my H and one for your X.
