Nic - I am not too familiar with your situation, but your title caught my eye.....
I can't even imagine what you are going through - I am so new at this and haven't even thought about the position that you are in.
I am so, so sorry for what he said and how he said it. Again, I don't know your situation...but an email? Gimme a break! Have a little class...have a little courage....sheesh....
I don't know how old your kids are, but I would think that this news will be a shock to them as well. Take care of them and take care of yourself.
Thinking about you, and hoping and praying for strength for you...
