When he gets upset about something I can give him support and advice and he's so resistant to me, but his friends can say the exact same thing I did and he'll come to me and say "Hey, guess what my friend told me..." and it's the exact same thing I told him that he was angry and resistant about!

I am very confused. Why does this happen? It makes me really sad.
It makes me sad that I am being loving and genuine and helpful and it makes him angry.
Lakadeema- Yes, it makes him even angrier and more resistant, so I stopped asking.
