I was at a place that was about to close and I really needed to get multiple assignments, labs and reading done for school, and I knew that everything in my area is closed, so I messaged my ex about directions to any place that's close by I can go to because she is the only person that I knew who lived in that area. She told me a place close by and was fairly understanding and nice about it.

Later a post on my feed popped up from her basically saying how ex's messaging you are essentialy worse than hitler/bin laden and that really hurt. I really do not know what I did wrong, and I don't know why she would be so hateful to me in such an indirect way without mentioning anything to me. I'm not a psychic, I can't read minds, but i'm not sure if I should just ask directly to see what I did or just remove from my contacts because she resents me so much
