A squaddle? hehehe sorry had to giggle never heard that term before.
Well I know there are no words that i can type to comfort you but I wish i could give you a big hug. What a horrible thing to be going through. Please don't blame yourself though for getting him involved in the corps, he made his own choice and died for our freedom. An amazing sacrifice. My DH is in the Air Force and I am so blessed to have met such wonderful people putting their lives on the line for our freedom.
IN the mean time, vent away, we're here for you! I'm so very sorry for your loss. Big hugs coming your way!
