I agree 100000% K. That is my point. I made a similar observation on Lola's thread last week.
I spent so long (almost 3 years now since I first suspected OW) working/trying/fighting to keep our relationship together, and it didn't work. I know I did my best, and tried everything I knew to try, so it isn't that I am upset about that part. I mean of course hindsight is 20/20 so I would do things differently if I could, but I can't, so I don't dwell on it.
But the things is, I am used to being in "fight or flight" mode, and now there is nothing to "fight" against. The battle to save the marriage is over, and I lost. I have gotten so used to 'thinking/trying/hoping/praying' that I am not sure what to do with myself now that I am out of that mode...
