Aita For Getting Mad That By Best Friend Isn’t Acting Like A Friend Anymore?

I have this friend, Joshua Jackson, and we have been best friends for what feels like forever! I already miss him! Well, whatever! I am a business person, starting my own art business! And, my expired business partner, David Underwood got fired, and he copied my business idea, and didn't change anything! He also got another Serenity to work with him! WHAT!? Joshua Jackson asked what I was going to say to him, then I told him, and made him promise not to tell anyone, then he told someone. I was hurt. THEN HE DID NOT KNOW WHAT HE DID WRONG! BITCH IF YOU NEED TO REPLAY THE FUCKING VIDEO IN YOUR BRAIN!

This is another story! I was confronting that Bitch David, right? Then Joshua didn't back me up on anything! he just laughed at me and said the fact that David copied my business idea isn't a big deal. I told him not to talk to me! I was so done! Then he applied and I forgave him.

Alright guys, Should I have been more cold hearted, or am I the Ass-Hole for getting mad at him in the first place? Let me know!
