What a supreme douchelord. It reads to me like, "Hey Kitty, I know you've just been waiting around for me, so here I am!" And just in case that's not enough, he's hitting you with what he knows is a sore spot so you'll be sure to contact him and get sucked back in. So 1) he's assuming you're desperately waiting around for him and 2) he's abusing the fact that you're a kind and caring person. I think I hate him.
I wouldn't blame you for responding via email something along the lines of, "I'm sorry things aren't going well for you right now, but I have moved on with my life. You know my feelings about Afghanistan, but I know that you will do what you want to do. I wish you the best." And then block him, fer cryin' out loud!
