Puppy - I read OT's email exactly how she did, for whatever that's worth. And if I had written such a letter to my ex-h it would have said the same thing yours did...even though the subtext OT wrote was the actual truth...because the sub-text are things that I just could not have said to his face.
Precisely as you are saying, my ex-h was the one who wanted sex all the time, so how could I tell him I wanted sex, but just not with him, directly in those words? I could never have been that honest with him because it would have crushed him. But that is exactly what I thought.
I was wrong about that though. And he could have been the one who helped me develop my sexual self. MC could have helped us find that out.
