rr22, I feel like you're telling my story here: "my H had built a whole world of stuff in his head that he thought I thought that I never thought. MINDREADING and PROJECTION. There were things that I had said that were twisted and magnified, things I shouldn't have said, and stuff that was utterly his issues being projected on me (and, I'm sure, vice versa me doing that a bit to him)."
I especially identify with the part about things I said that were twisted and magnified. I've had that happen several times. Never mind the times he did or said similar things. He was joking then! I, on the other hand, was allegedly being completely serious and intentionally cruel. The same rules do not apply to both of us, obviously.
Here's the big question: is his guilt a good thing or a bad thing? In a way, I think his guilt only causes him to blame me more. If there's a good side to his guilt, then I'd love to know!
