I wish I didnt, but I did....

I feel so terrible right now. My brother is one of the most important people in the world to me. He wants so badly to have a beautiful, christian, good spirited woman. I really and truly thought that I had found someone perfect for him. It seemed like it was a great match. Apparently, I was wrong, and now my brother is hurting. I let this into his life and I feel terrible for it. How could my friend just dismiss such a wonderful man like that? Yes, he has his flaws, but they are minimal. He is a phenomenal person and ANY woman would be lucky to have such a wonderful person. I am sad. I wish things would have worked out, but as it seems, she is just dismissing him like he was not important to her at all. It hurts my feelings to see him hurting so much. He thinks I set him up with her just to chase away his ex. Entirely not true. I genuinely thought that she would be good for him. And good to him. I was wrong. I wont ever try to hook my brother up with someone again because I do not want to be responsible for his hurt. It makes me mad that she would do this to him, yet she is my friend. :-(
Where do I go from here?
