I had this EXACT issue last year! I lost my friend to popularity though. But everything gets worse before it gets better! AND everything that happens, happens for a reason. If "Sue" is doing this to you, then she isn't a true friend. As people grow and progress, a lot of the time, they change. It's not always what we want, but it's just what happens! If things don't get better with Sue and she continues to have this, "I'm better than you," attitude, then you honestly don't need her as a friend. Friend's are there to help you up, and keep you smiling, not to knock you down and place your mood down! Now, Jill. I think that she's just going with whatever makes her more noticed. Girls love to be noticed, and do whatever they can for attention most of the time! Jill probably just wants to fit in, not noticing how much it truly hurts you! To be honest, if Sue continues her attitude the way it is, you should not continue to try and mend then friendship. It'll lead to more hurt! I understand that having a best friend for that long, losing them is the worst. But in the end, they're the ones who realize how much you really meant and how horrible they treated you. My old best friend ended things with me a month before her birthday, but I still showed up to see her and give her flowers, because I told her I missed her. I didn't ask for our friendship back, I just simply let her know that I forgive her for the way I was treated and that I'm sorry for anything I did to hurt our friendship. Then she realized how much I did mean to her. And how good of a friend I was! Your friend will eventually do the same!! Good luck! Hope I helped!
