I hate to ask this but could you give a more summarized version of this email? I realize you had a lot of reasoning you wanted to cover on the why's but I frankly got lost several times. That makes it really hard not to respond in ways which are overly emotional and not helpful. Anything I wrote would start with me trying to summarize what was written but failing to do so, or I would end up trying to pick apart different paragraphs in non-helpful ways.
