I don't have a brother, only an 8 yr older sister, but if it was me I would go down to his level...I would sit him down and tell him he's being an ass and you are trying very hard to develop a better bond. Tell him how hurt you are by his words, but not as if you are begging for sympathy or for him to open up. Tell him that when he's done sulking like a five year old potty mouth, HE can try getting in touch with YOU.

but that's juts my .02
