Okay, I am going to come in (because I am sooo bored at work today) and play Devil's Advocate a little...
He is missing you as much as you are missing him. This is all as hard for him as it is for you, and anyone who has been in a long distance relationship has, at one point or another wondered if they were doing the right thing and if they could cope with the heartache. There are threads on this board from ladies wondering if they should cut their losses, despite the fact that they love their boyfriends, simply because they didn't know when they would be together again and because they thought that perhaps the heartache would be less if they just called the whole thing off. This is a perfectly reasonable attitude to have, and it could be where your boyfriend is coming from. Yes, he has been insensitive in the extreme in the language he has used, but we all make mistakes when we are upset.
Perhaps he is worth giving the benefit of the doubt, but I do think you need to talk, on a phone, and not just do this by e-mail, as so much can be misunderstood when you can't hear the tone of someone's voice.
I hope it all works out.
