What should I do about this friend?

[Hailey]

Try to talk to them. Tell them how you feel. Maybe they don't notice that they are treating you differently. Or if they are doing it on purpose, maybe you don't need them anyway because that isn't a very good friend. If you can't talk to them in person, maybe text them or message them on facebook or write them a note. If you feel like it is worth fixing, don't give up.
