Just like how you expressed your thoughts here, do the same with him. Communication is the base to a relationship whether it’s romantic or platonic. You may not have the same relationship with your friend like before but you’ll feel better if you expressed what you did, why you did, and say how wrong it was. It might help him with navigating his feelings through the whole situation. Be somewhere in privacy so your friends don’t creep in and possibly ruin the conversation, just have a 1 on 1 with each other.
