So my bestfriend who I trust her for everything is mad at me idk what I did to her I found out yesterday because she don't text me back the last time I texted her she was like oh wat do u want and she texted me like this -.- and I'm like oh hi but that was the last time I texted her and I also found out cause I went to her Facebook profile and I seen the friend button and it said add friend and that's how I know that she is mad at me like maybe I think she don't want too talk to me because this girl who used to be my ex girlfriend I told my ex bestfriend that she hurted my feelings and my bestfriend did everything to talk shit to her but now that I'm going out with my ex maybe my friend found out and she got mad at me because maybe she though I was lying or something else so what should I do I mean last time she told me I found out ur with ur ex I'm not ur friend no more bye and I even cried but she gave me a chance and forgive me but now that it happen again she really mean it

Your friend is not a true friend. She is an immature kid. Cut your losses and move on. Find better friends
