Makes it easier for your brothers here at the forum to respond!
Okay, so he is moving away you say and it is likely that you will never see him again?
If that is the case, my advice to you is to get closure on this friendship! Tell him the stuff you have told us, and say to him that you would like to part ways as friends.
I have personally had some "friends" move away with whom I didn't have a good relationship to in the end, but when I get closure and talk to them and patch things up, I feel better about myself and that is the priority here. Do it for yourself, not for him.
Let me know what you decide and how that works out!
Sincerely
A
