Would it help you if you imagined you were writing this letter to someone else with why who have a good relationship?
Good advice from Wonka on homework to do some more work on the letter and from the above. It read very transactional to me which is more of what is not working with your W.
As at point from my first read of the letter: You pointing out the "data": you have him 5 days and I have 14 was a turn off to me. But I did like the idea of you asking for compromise.
