Pads, did you ever think that with something like this you're unintentionally sending him the message you don't want him in your life?
I know this is a happy thing for you. And I will be happy for you both because I love you and want you to be happy. But, I know I'm hurt that I couldn't be there to see my best friend get married. How much more do you think it hurts your brother who already believes he's just an after thought to you?
And, I'm sorry I didn't say Congratulations sooner.
