Is OTHER wrong in the post ? POST : Here's the background. I (26M) used to date at coworker on a different shift (26F) for around 6 months before she broke up with me. Yes I'm aware that you should never date your coworkers but I really liked her and at the time she liked me so we gave it a shot. When it didn't work out, I still had strong feelings for her and having to still see her 4-5 times a week, even if it was for 15-30 min wasn't exactly fun. Yet, I still had to be professional. I talked to her when I had to and try to acknowledge her when she walked by, but that was it. No small talk. Everything was brief and to the point and it worked. Despite seeing her, I managed to get to a good place and start another relationship over half a year later but I never changed how I interacted with my ex. 

&amp;#x200B;

Fast forward to the last three months. My manager wanted to dust off an old project I had work on two years ago and implement it. However, because my ex was involved in it as well, I had to work with her. I began sending her my edits and revisions but I never got a reply back that was helpful. She would ask for a sit down to talk about it but never committed on a date or she wouldn't even reply. Then suddenly, I found out last month she was leaving and today she let loose that I'm to blame for it. She says it's my fault for not helping her, going around her back with my project and overall being stressed out to the point that she had to leave. However, I never knew how stressful at work it was for her and she never asked me or anyone for help. She also told me that she wrote her own version of my project but because management wanted mine, she felt she had wasted her time even though it was clear from the beginning it was my project that was going to be implemented. Sometimes I feel like it's my fault for not being able to be her friend after the breakup and talk to her like before. 

AITA?
