This might be a very poor attempt on his part to underline what a much better friend he is. Might have been fishing for a shower of compliments and thanks.

I don't know your friend, but the best way to address an issue with me is to do so very calmly and without it being personal. If I somehow get the feeling I'm being rejected (I'm using a strong word on purpose) for something I did that seemed totally normal and inconsequential, I will not take it well. I'll feel challenged in my whole being and I will either feel very bad or cut off communication for a bit until I get over it (if I do). Though, granted, I'm not the most emotionally mature person. Calm, logical and by avoiding personal attacks is the way to go, as far as I'm concerned.
