Input: Me and my girlfriend ( now ex ) used to work at the same place but then she got a new job so she had to relocate and have met other trainees the day she reported to her new job. Her batch have known each other for two weeks or so.

One day she was walking to the train station after work and one of her male trainee happened to be behind her. So he texted her on IG saying that "she has a beautiful back", I'm not sure if she responded to his message after he texted her to chat. But then she screenshotted his text to her and posted it on her Instagram story with an additional caption saying "being chased by a handsome man" along with some GIFs of a heart-eyed bunny. I saw her story and I felt disrespected as the way I see it, she is directly flirting with her male colleague and furthermore posting it on IG.

So I texted her and asked her what's all this about and she replied saying that I have nothing to worry about as he is only a friend from work. We had an argument over that story and she defended herself saying she should be allowed to socialize or post anything on her social media and that I should not be controlling her. I shot back saying this is not about controlling her but about her not having any boundaries between socializing and flirting openly. After that exchange, she told me if I wanted to control her, I should look for another person to control so I broke it off on the spot.

AITA?
