if she feels that way and has expressed it,I think there is hardly anything for you to do to make it better.people just grow apart sometimes and it's normal.Maybe after a while of being away she will realize she misses him and knows she wants to be with him?Had they ever talked about marriage?children?maybe you could talk to her and find out what is going on in her mind.you are her best friend,correct?well,best friends talk.All you can do is be there for the both of them!

silly. There isn't anything you can do. Once someone makes up their mind it is hard to change it. But in time she might feel differnt. There might be more behind it then what she is telling you because he is your brother. Even though she is your best firend, she might keep things from you because he is your brother. I would just remain her friend and tell her that, she might open up more with you. I'm sorry.

Thank you for your comments. I don't know why this affects me so badly. I feel like I am watching a house burn down with two of my favorite people inside and I am doing nothing to help them. I have been crying all morning. What a sap I have become in my old age...

awww sweetie,I hope everything turns out alright.

After much soul searching, I think I have figured out why this bothers me so much. My brother is a delicate boy in a hardened shell. He has very soft innerds, and I worry how he will come out of this unscathed, as this is the first person he has really lowered his guard enough to love. I feel very protective of him, and have only ever wanted the best for him. I took care of him for much of our lives, and I guess I feel a little "mother hen-ish" toward him. She is my best firiend, but I guess I am a little bit angry about this (although, I truly have no right to be). I feel inadvertently stuck in the middle of all of this. Furthrmore, my irrational emotional part wants to say what the frock?? HOw could you lull me into thinking this was going somewhere and how could you dupe us all into thinking this was for real (again, this is faulty thinking, but since when are emotions based on logic?) I called the little brother this evening and told him most of this. I wanted to let him know that I was here without any judgement on the matter, that I will not meddle in his affairs, but he can call to talk, come over, mooch dinner, eat my food, borrow my furniture or sleep on my couch whenever he wants. My heart is completely breaking for him. I hope that I am done crying soon, because my head really hurts. At least it's allergy season and I have an excuse for the way I look. Thanks again for your thoughts on the matter.

awww,I hope you feel better son and i'm also very glad you let your brother know that you are there for him,tahts an awesome thing to do!
