boyfriend talking to your bestfriend

Mckenna
so my boyfriend talks to my bestfriend all of the time.
yet when she dated 2 of my friends that I introduced her to she blocked me on all of their social media things so they couldn't talk to me and so I couldn't talk to them. she was his number one bestfriend on snapchat. I said something to him about it the other day and he deleted her on snapchat. idk, I just need input on this. would anyone else be mad?
