Is AUTHOR wrong in the post ? POST : So my (M23) girlfriend (F22) of 2 and a half years and I have been fighting a lot recently. We decided the best thing to do was break up, and that I would be moving out. That was 2 weeks, and today I got the rest of my stuff and left. 

Yesterday at around 8 at night, she got a call from her sister saying that her dad (only living parent) had died in a car crash. She immediately broke down after hearing the news, and begged me to stay, saying that she didnt know if she could get through this. After a few minutes of consoling her, I told her I was still leaving, and that this hasnt changed anything. I told her if she needed someone to talk to I would be there, and that I wanted to be at the funeral because her father was a great guy. She told me not to bother, and that I should just leave that night, so I did. 

Today when I came to get the last of my stuff she seemed broken. She wouldn't talk to me at all, and I felt like a total piece of shit. After I left, a few of her friends texted me saying I was a selfish douchebag. I felt that staying would cause an even messier break up than it already is. So AITA?
