Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: While the issues I'm gonna tell you about have been resolved, I'm unsure if I was in the wrong here and this situation is still messing with me. I have trouble judging what's socially acceptable sometimes, so if you decide to comment, please explain things so that even a robot could understand.

So there I was in my early 20s, a young woman with very few friends, only one of which lived near me. Let's call her Karen. Karen wasn't a close friend of mine. I always saw her getting into some kind of drama with one of her 100 "besties". Against my better judgement, I hung out with her. Through her, I got to know a dude she'd been friends with since kindergarten. At the time he was in a relationship with one of Karen's close friends.

Dude and I became friends. I found him attractive but obviously didn't wanna mess up anyone's relationship, so I was really careful to not overstep my boundaries and kept things strictly platonic.

A couple of months later though, dude's girlfriend breaks up with him and tells him she simply doesn't love him anymore. Meanwhile, dude and I have become pretty close friends. So when he tells me what happened I did what every good friend does. I listened to him when he needed someone to talk to, tried to cheer him up, and invited him out to get away from their shared apartment to get his mind off things.

We quickly realized that we had feelings for one another. Things moved fast; too fast. He hadn't had time to get over his ex and I was an inexperienced fool. We had only been a thing for about two or three weeks and he broke up with me. Of course he needed space. I was devastated.

Then I got a text from Karen. She was livid. How could I have dated one of her friends and not tell her?! So soon after the two of her friends had broken up, no less! She was disappointed in me, she thought we were friends. She was entitled to know about it.

All I could manage to say was that I didn't mean to keep it a secret but that things had been moving so quickly. I had been afraid that I might have just been a rebound and wanted to give the relationship some time before telling everyone, instead of telling people we're official to then go around a few days later being like "oh lol, nevermind". Besides, she definitely was not entitled to know every single personal thing that was going on in my life. I also told her I didn't appreciate her berating me like that, so soon after having been broken up with. I was not in a state of mind to deal with even more emotional stress.

We weren't friends anymore after that. She tried to contact me again after dude and I started seeing each other again, but I figured she just wanted to get all the info to start even more drama.

People seem to take issue when their friends see each other. Did Karen have a point? Should I have told her, despite my insecurities about the relationship? Was she entitled to know two of her friends were dating? Had I really been a horrible friend for that? **Am I the asshole?**

not telling a friend that I was dating a mutual friend
