Barney-- this morning I'm thinking more about what I posted to you last night, and in fairnessm, I need to add that I was in a similarly situation. I did not have the balls to leave. I know how hard it is to be in the situation, and personally, nothing I tried worked or even made much improvement. (and in my case, it was a SSM but there were other issues as well)
I resigned myself to "laying in the bed I had made" and knew that my life/marriage would never ever be better than a 4 on a scale of 1-10. I thought it would be "frivolous" to actually leave the M, when there were still some good things, and we were mostly civil, and he had not done horrible things (ie beaten me, or committed crimes). Short of those heinous things, I did not think I was "justified" in leaving-- so I had to settle for being permanently, hopelessly unhappy.
So I just wanted to tell you, that while I tell you to be strong/honest/true to yourself-- I was not able to do it for myself. I WISH I had been able to, but I wasn't-- the only reason I'm out of there is because HE decided to end things. That sort of "stings" too-- even tho I know it was a good thing, in the big picture.
