Boyfriend and a boy that is a friend

So me and my boyfriend have been dating for 4 months and me and my other friend who is a boy Blake have known each other for four years I had a crush on Blake but then that only lasted maybe a year but just the other day he told me that he liked me. But my boyfriend Cody and I have a connection and I no longer have a crush on Blake. I don't even find him attractive anymore. Anyways they have only met once in person and they're constantly bickering over the phone and stuff. Today I had enough with being the middleman in told to talk it out so I made a group chat on Snapchat with me and them Blake is 19 Cody is 16 and I'm 17. I need help.
