Sometimes it's easy to say you're over it as if it's a self reassuring, reconcilliatory band-aid. But it isn't. Especially in relationships where you've found yourself lied to, betrayed, and devastated. It might take part of a lifetime to completely rationalize what happened after you've worked past the emotions. GG's have an amazing capacity to get over it and move on. Partly b/c of their support network, partly because they can directly deal with their emotions. I think in part that ability sometimes leaves them seemingly absolved of the carnage and mortal wounds they inflict. You can get over it, but it's still going to take time to recover.
