I have weird feelings about my recently outed best friend
Why do you have weird feelings about your best friend? Does him being out have something to do with it?
He has been acting like an asshole for a long time now.
You should be nice you your friends. People make mistakes and might need help to learn from them. It might be good to trust your hunches and ask them why they are acting weird.
It's pointless. I just might need to get over these feelings and ignore it.
Your friend is still your friend. Just remember that nothing has changed.
