You know this letter would have been decent if you used better grammar, spell check, and left out all the childish names. I understand your frustration. My ex-husband was in the navy and when I remember how happy I was when he would tell me he was finally coming home. And of course how upset I would get when he called me up that day and told me it would be another week.
On another note, be thankful that he's even coming home. Do you know how many widows and widowers would love to be in your situation right now? I have a very close friend who lost her husband in Iraq. He was a marine. She is now a single mom of four kids.
And while you have a valid complaint, nobody will take this letter seriously the way it is written. Try calming down and rewriting it.
