Well, there's separated, and then there's separated. I was separated for two years before my divorce was finalized, but it was completely over from the day he filed soon after he left. All the DBing, drama, reconciliation attempts etc in our case had gone on in the years before he left - once he was gone it was quickly over from an emotional sense. The ONLY reason it took two years to get divorced was that the paperwork side of things was such a pain in the neck.
So - I know my sitch wasn't necessarily the norm, but I'm just saying some people are still legally in the separation stage but emotionally well divorced. Similarly, some people have divorced but not let go yet. Which do you think she is?
