there is a person i've been friends with for 4 years now, but a couple of weeks ago she dropped me and and all of her other friends when she started talking to one of my ex-friends. according to him she is tired of crying over me and says that i hurt her but is not being specific about how i hurt her. from what i can recall i've done nothing that would keep her from wanting to be my friend. she is also being kinda judgemental saying one of her friends was kinda freaky and saying she didn't like another one even though she never met her.
i ask for your advice on the situation. she has been my best friend for 4 years and i still consider her to be my best friend.
what should i do since she won't talk to me?
