I'm so sorry to see how much you are hurting over this .. i know how much he means to you. It does sound like he is putting you through a whole heck of a lot ... and i think that you've done the best thing by sending him that email. I dont know exactly you're relationship, and i know that all relationships are complicated, but i do truly believe that truth is the best option. Not that you are lieing to him by any means, but unless you tell him of these things that are bothering you, he may not know. Some people just are not as observant of others feelings ... he may be able to in some aspects, but i'm sure he doesn't realise he's hurting you emotionally ... he's doesn't sound like the type of guy who would do that intentionally.
I may not know what it feels like to have a special guy friend that i have to leave ... but i do know how much it hurts when someone you love leaves you in some shape or another. It is not an easy feet by any means, but i know that you can get through this. You are so strong, and while it may be hurting you so much now, it won't always be this way.
Talk to him while he's still here, and do you best to let him know how you're feeling.
