Given a post that is a real-life anecdote of a complex ethical situation and a question asks if AUTHOR, NOBODY, EVERYBODY, or OTHER is wrong in the situation. Answer the question and classify your answers into yes or no.
One example: Is AUTHOR wrong in the post ? POST :  Pretty much was hanging out with two friends. I was watching the Lakers game. They won at the very last minute and I immediately hopped up and celebrated. Before I could even finish celebrating one friend started going on about how the Lakers suck. It just pissed me off so much I screamed at her to get out my room until she left. 


She knows I'm a huge fan and she likes them too. She was only saying it to antagonize me. Am I the dick here?
Solution is here: yes
Explanation: It is very rude to shout at someone and ask her to leave the room even if her comments may have antagonized the author. Hence author is at fault here.

Now, solve this: Is AUTHOR wrong in the post ? POST : WIBTA if I tell my friend that he is being cheated on?

I'll try to keep this story straight with names, it might get a little complicated. There's me, my gf (M), my gf's roommate (A), my roommate (T), and my friend (E).

Backstory: Me, E, and T all good friends two years ago, freshman year of college. We hang out all the time, life's great. A and T meet and start hanging out, one night E asks me if I wanna come to the hookah lounge with him, A and T. I accept, and I meet A for the first time. Immediately she's off-putting. Making weird comments how how muscular I am, in front of two guys that clearly have huge crushes on her, and just overall having no sense of what to say in the room, really killing any vibe, you probably know the type. Anywho, I found out around present day that A told M right before she got with T that she was going to choose E, saying that "he's THE ONE", which is batshit crazy seeing as they have known each other for like two weeks and are 18.

A actually ends up choosing T, and they have a long and horrible relationship filled with miscommunications, fights, drama, etc. M and I are on the sidelines of this because I live with T and she lives with A. At least once a week T goes to break up with her, but for some reason A thinks it has to be agreed on, and they end up fucking and just resuming the cycle. So much drama and it's pathetic because of how idiotic they act. They have no boundaries, A has taken condoms from M and I and denied stealing them, T never does anything for anyone but himself. it makes everyone so tired of them. Anyway, over last summer T finds a girl he actually likes for reasons outside of the bedroom, and breaks it off with A for good. T enjoys his new girl, but one night A comes down to our place BLASTED drunk and hits her head, passed out. Me and a friend take her to the ER because they cant afford an ambulance, and we are good friends, and don't want to see anyone die tonight. This seemed to be a wake up call for A. she goes home and lives with her parents for a bit, eventually comes back and see,s changed.

A ends up getting with E, and they start spending all their time together, despite E seeing how A and T played out. Then, 2 days ago, T and her meet up at 11pm to "delete their messages/pictures together" (wtf). They end up staying the night at her place, and staying together locked in her room for the entire day and the majority of yesterday. We know they had sex, since M's friend saw condoms that aren't the brand A and E use (A tried to give M some back for the ones she stole), and given their history no one is surprised.

T also left a big pile of his disgusting dishes in the sink for a week, and I put them on his bed last night so they would be out of the sink, which he got mad about, so I'm pretty much done since I asked him to clean them up 3 or more times. I would not feel bad about letting my friend E know what's happened this weekend, but WIBTA?
Solution:
no
