My Friend Yelled At Me

This is a follow-up post. Basically in my other post I talked about how my best friend hooked me up with her other best friend a while ago and2 months ago he broke up with me. I tried to hang out with her earlier but she said she was hanging out with him. I told her it hurt me. She said she was friends with him before we dated and she's not gonna stop just because we broke up. She came over to see me about an hour ago and she looked frustrated already. She just wanted to chill and drink some wine. We drank wine and I start telling her how he didn't treat me the best or make me feel loved and that I don't see why she's friends with him and saying he's not a good person. I saw her start to roll her eyes. I asked what her problem was and she starts yelling saying "My problem is I'm tired of you both! I'm sorry, but I'm tired if hearing about how one or the other treated you so bad or how terrible the other person is! I just told him off for talking about you! I didn't come here for the same shit! You both need to get your shit together and stop trying to make me hate the other! Because at this point I'm very close to cutting you both off!" She grabbed her stuff and left after that. I literally got yelled at just for venting and to know he's been talking shit behind my back. I'm not trying to be a bad friend, I'm really not. I'm hurting though and it feels she doesn't understand.
