can anyone please suggest something? My friend is mad at me. He says he can never trust me again, but I don't know how I broke his trust!

We were fine in the morning the day he started to ignore me and started to tell me to f* off. He started to cuss at me at around the afternoon. I don't really know what it was, and I don't know how to find out OR how to gain his trust again! He's mad at me and one of my other friends but one of his friends informed her that he'll be fine from the next school day, but he REALLY hates me!

My ex-bf came into THIS as well, and now he's just ruining my life! He was the one who told me my friend said he can never trust me again, and I really don't know what's wrong. I think it could be this thing I did to my ex (bad mouthed him. B.A.D) cuz my friend said he never expected that from me, but I'm not sure! I'm really confused and i'm sorry if I'm confusing you but I've been fighting this for a LONG time and I just don't know how to win this one. I really don't wanna lose my friend, though I probably already have...


If any of you can think of any way that I can gain my friend's trust again, I'd really appreciate it! Cause i'm really sick of crying. :'( </3
