<human>: Give me a shortened version of the text

So I told my best friend that I really do like her, and she said that she could only see me as a friend. Ok, great. I am completely find with that, but the problem is that she and my best guy friend are basically starting to date now, and I cannot stand it. It makes me so sad whenever I think about her. 

Most of you will just say, oh don't text or talk to her, but I cannot do that. We are best friends, we talk for hours every single night. Cutting comms off with her is something I really do not want to do, but she brings me so much pain whenever I think of her.. I have no idea what do to. Advice? Please, I am struggling.
