40 times and nothing.?

The reason your friend Dallas feels this way is probably because he feels betrayed. He probably relied on you to keep what he was telling you private. Since you have tried to apologize, try again and if he rejects you, then just ignore him for a while, and ignore what he thinks as well. It's not what he thinks, or what the rest of the school thinks, it's what you actually did. He might be hurt, but since he is friends with the other girls, and they don't hate him or anything, he might be willing to forgive you in the future. Just try giving it a rest, and then maybe if he shows signs of forgiving you, call him and start off by saying you're sorry. Although you made a mistake, the first step in him forgiving you is you admitting you did wrong. As hard as it can be, you have to let him know you are sincerely sorry for what you did. It's understandable that you wanted to share your information with your best friends but remember that Dallas was your close friend as well. Good luck!
