Should I go to a Christmas party of a friend who I no longer speak to?

 so long story short, I have this friend that she always has an attitude. The last time I spoke to her, she ruined the girls trip by canceling the plans a few days before. She always has to have her way, if not, you won’t be happy, and no one else around. You will not be happy, sometimes I miss her but EH. It’s always the same cycle with her. So, a mutual friend who I met through her, invited me to their Christmas party at their apartment because they stay together. Now this is not the friend who I’m not speaking with, but the other girl. I said, thank you for the invite and that was really it. So, then another friend of ours says “ I didn’t know “blank “invited you to the Christmas party.” That seems like I was brought up in a conversation among them. So more than likely was talked about because they’re messy. SO, I just received a text from our mutual friend asking if I was coming to the Christmas party, I haven’t answered. What do you think?
