I want your opinion

Because you are friends, you strictly have to talk about this. there is no problem without solution. You can initiate the talk if you want, or it is better that you initiate it because i feel you are bothered. I am sure things will be clear since you are friends.

Mahmoud4ever, in my very humble opinion, I truly feel that you should immediately talk to your friend to finally patch things up between the two of you, especially if you really still want to recover and restore your old friendship. Staying away from your friend, to be sure, would obviously not resolve the conflict between the two of you, since your problem would not magically go away by simply ignoring it, but it would just continue to linger and perhaps even constantly bother both of you. I really believe that every problem or "damage", as you put it, clearly and reasonably talked about could eventually be solved. Just be sure, though, that you would diplomatically talk to your friend, if ever you do decide to talk to him, and carefully make sure to fully empathize with him so that you could hopefully resolve your problem more easily. In the end, whatever your best decision would be, Mahmoud4ever, I could really only wish you the very best of luck.
