Open eyes, I felt the same way you did, until I read his response on her wedding day, which was simply "big problems", which to me indicated he was still focused on himself. I too found the email exchange hopeful, but up to a point. I would see them maybe starting off going to therapy together, but I think the brother has a longer way to go, for whatever reasons, so it would end up him breaking off for individual therapy. But I don't think you and I are that different in how we reacted and understood these posts, honestly - more similar than different. I agree with what you said, but then focused more on the negative end, where it does not come to closure, and why.
