Is it in appropriate to out your spouse’s affair on social media?

I’ve known it for a while, but just pretended it wasn’t happening. For like half a year now, I’ve stayed home on weekends (my preference) while my spouse goes out to party. I finally mustered up the courage to poke around. I barely turned over any rocks and there it was right in my face. Turn’s out they’re having an affair with one of my oldest and closest friends. I’m so upset. I just want to say hey world I just found this thing happened to me and then get divorced. That way everyone knows what happened and no crazy stories can be told about me without folks having the other side of the story. Same for when I cut my bestie from my life. But then my over exaggerated sense of moral decency kicks in and I feel like that’s taking things too far. Advice wanted, please.
