My brother once dated a good friend of mine and at first I was excited for them. Then my friend stopped being my friend and started acted superior to me and felt I was beneath her. When they broke up, we were never friends again. Since then I've forbidden my brother to even so much as to ask me about any single friends I might have. And if my friends ask to be set up with my brother, I give an evil eye and say, "I don't think so."

Anyone been in such a situation? How did it turn out?
